The authors studied 37 consecutive patients with primary Sjögren syndrome and normal chest radiographs. Thin-section CT images were analyzed using a semiquantitative grading system. The presence, distribution, and severity of 9 morphologic parameters were assessed.

[CT-phlebography. A new method for the diagnosis of venous thrombosis of the upper and lower extremities].

Unlabelled: Spiral CT venography is a new method in vascular imaging, which is an accurate tool for the evaluation of deep venous thrombosis in the evaluation of deep venous thrombosis in the lower and upper extremity.

Materials And Methods: 102 lower extremities and 12 upper extremities were evaluated for deep vein thrombosis using spiral-CT-venography. The results were compared with findings of ascending venography, color coded duplex sonography and clinical follow up.

[Preoperative imaging of varicose veins of the lower extremities. Classical pattern of insufficiency and its clinical use].

Unlabelled: Venous varicose are one of the most common diseases in industrial countries today. New surgical strategies, tailored to a patient's specific pattern of venous incompetence require more detailed preoperative imaging.

Methods: In this review of current literature we analyzed the value of ascending venography, color coded duplex sonography and descending venography for preoperative planning of varicose surgery.

Spiral CT evaluation of deep venous thrombosis.

Spiral CT venography is a technical innovation in vascular imaging that can optimize vessel contrast in the deep venous system and, therefore, is an accurate diagnostic tool to detect deep venous thrombosis. Compared with conventional venography, the amount of contrast material can be reduced by 80%. While using spiral CT as the primary imaging technique for the detection of pulmonary embolism, the cause of embolism can be evaluated within a short period of additional imaging time without further patient mobilization.

MRI versus lateral stress radiography in acute lateral ankle ligament injuries.

Purpose: Our goal was to compare the abilities of MRI and stress radiography to detect the extent of recent lateral ankle ligament inversion injuries.

Method: In this prospective study, 60 athletically active patients (aged 18-45 years) with recent inversion trauma (< or = 7 days) underwent stress radiography and MRI. In 15 patients, the MR findings were reviewed at surgery.

[Ultrasound morphology of the Achilles tendon and differential diagnosis].

Aim: To correlate sonographic findings and clinical disorders of the Achilles tendon, considering newer aspects of their etiology and pathogenesis.

Method: In a retrospective cross-sectional study the sonographic findings in 52 patients with tendonitis, heel swelling, or suspected rupture were analysed and correlated with the final diagnosis. Tendon lesions due to lipid storage diseases or rheumatic diseases were analysed on the basis of reports in the literature.

Deep venous thrombosis of the lower extremity: efficacy of spiral CT venography compared with conventional venography in diagnosis.

Purpose: To compare the efficacy of spiral computed tomographic (CT) venography with conventional venography in the diagnosis of suspected deep venous thrombosis (DVT).

Materials And Methods: In a prospective study, 52 consecutive patients with clinically suspected unilateral or bilateral DVT were studied with CT venography and conventional venography. In cases in which conventional venographic findings were inconclusive, color-coded duplex sonography and follow-up examinations were performed to make a final diagnosis.

Preoperative imaging of lower extremity varicose veins: color coded duplex sonography or venography.

We prospectively examined 137 limbs in 112 consecutive patients with clinical evidence of severe varicosis by color coded duplex sonography and ascending venography (including varicography in 48 limbs) to evaluate the diagnostic capabilities of color coded duplex sonography in the assessment of venous anatomy, variant varicosis, postthrombotic changes, and incompetence of the superficial and perforating venous system. Additionally, descending venography was performed in the first 52 limbs and compared to color coded duplex sonography in the diagnosis of deep and superficial venous reflux. Variant venous anatomy (21 cases) was missed in two limbs and misinterpreted in one limb by ascending venography compared to surgery.

[Differential diagnosis of diseases of the Achilles tendon. A clinico-sonographic concept].

Ultrasound of the Achilles tendon is a suitable means of differentiating various diseases of the tendon and the surrounding tissue. Different forms of degenerative disease (tendinitis, peritendinitis or bursitis, fibroosteitis, and Haglund's disease) can be discriminated from rheumatic and metabolic diseases. Congenital and developmental abnormalities can also be detected.

Complications after emergency tube thoracostomy: assessment with CT.

Purpose: To assess the spectrum of complications after emergency tube thoracostomy (TT) and show the role of computed tomography (CT) in detection of these abnormalities.

Materials And Methods: CT scans, chest radiographs, and clinical data were reviewed in 51 patients (77 tubes) who underwent emergency TT after trauma. CT scans were analyzed for chest tube malposition (CTM) and persistent pneumo- or hemathoraces.

Varicose vein stripping--a prospective study of the thrombotic risk and the diagnostic significance of preoperative color coded duplex sonography.

Insufficiency of epifascial veins promotes venous ulceration and increases thromboembolic risk in general surgery patients. Epifascial varicose vein stripping is therefore considered the most effective prophylactic procedure. Thromboembolic risk of patients undergoing this surgical procedure has not yet been prospectively evaluated but appears to be lower than in general surgery patients.

[Magnetic resonance imaging of breast implants. Significance compared to mammography and ultrasonography].

Magnetic resonance imaging (MRI), mammography and ultrasonography were performed in 44 consecutive women (mean age 45 [29-70] years) with a total of 73 silicone breast implants. The implant had been inserted after mastectomy for cancer in 15 patients, for cosmetic breast augmentation in 29. MRI proved to be superior to the other two imaging modalities with respect to assessing implant content, capsule and surrounding tissues.

[Bronchiolitis obliterans organizing pneumonia with acute respiratory insufficiency].

A 22-year-old woman was hospitalized because of fever of 39 degrees C and increasing dyspnoea. The chest radiograph demonstrated coarse confluent opacities bilaterally. Despite antibiotic treatment the condition deteriorated acutely after 2 days.

[The long-term changes after the implantation of silicone breast prostheses].

In a prospective study 60 patients with unilateral or bilateral mammary implants underwent mammography and sonography. Location, form and structure of the implants were evaluated. Additionally capsular fibrosis and its influence on the imaging quality of parenchyma was scored.

[Extensive intraductal components of invasive ductal breast carcinoma--value of mammography].

The presence of an extensive intraductal component (EIC) in patients with infiltrating ductal carcinoma is a major factor for predicting local recurrence after breast-conserving surgery and radiotherapy. A retrospective study including 67 consecutive cases of stage I and II infiltrating ductal carcinomas of the breast was conducted to determine the predictive values of mammographic features associated with the presence or absence of EIC. 43% of the lesions contained a pathologically verified EIC.

[Bronchiolitis obliterans accompanied by organizing pneumonia: radiologic diagnosis in a case of a 22-year-old female].

Case report of a 22-year old patient with most severe idiopathic bronchiolitis obliterans and organising pneumonia. We discuss the diagnostic algorithm and emphasise the role of CT.

[Phlebography of the leg veins. Study quality and sources of error].

In a retrospective study, 198 contrast venographies were evaluated by two blinded observers for quality of opacification of the venous system and quality of documentation. There was good correlation between the two observers in 91% of the cases. They found an adequate contrast quality in 183 cases (92.

[Imaging procedures in varicosities].

A prospective study was performed to compare the diagnostic potential of color-coded duplex sonography (CCDS) and that of ascending pressure phlebography (APP) in 61 patients before venous stripping. Varicosis of the long saphenous vein was correctly diagnosed and graded by CCDS in 87% of cases, and varicosis of the short saphenous vein in 97%. CCDS was inaccurate in 3 of 4 cases of recurrent varicosis of the long saphenous vein.

CT and MR accuracy in the detection of tumor recurrence in patients treated for ovarian cancer.

Objective: The aim of this prospective study was to evaluate the accuracy of clinical examinations (palpation/determination of serum tumor-associated antigen CA125 level), CT, and MRI in the detection of tumor recurrence in patients with treated ovarian cancer.

Materials And Methods: Twenty-four patients who had been treated for ovarian carcinoma were prospectively examined by clinical means (palpation/serum tumor-associated antigen CA125 level), CT, and MRI to assess their accuracy in detecting recurrent disease; results were correlated with surgical/bioptic/pathoanatomic findings. Nine patients had relapse; 15 women were disease-free.

[Renal osteodystrophy: the spectrum of the x-ray symptoms in modern forms of kidney transplantation and long-term dialysis therapy].

Plain film radiography and microradioscopy represent standard imaging for diagnosis and grading of renal osteodystrophy. The aim of this retrospective study was to evaluate the effects of modern therapeutic regimens on skeletal abnormalities as diagnosed radiographically. 198 patients were investigated.

[Pseudo-stenosis of the renal artery: a possible defect of color Doppler sonography].

The diagnostic value of pulsed Doppler sonography for the detection of renal artery stenosis was questioned by recent studies. Until now, the diagnostic value of colour-coded Doppler sonography of the renal arteries is not clearly defined in relation to pulsed Doppler. This study deals with specific problems of colour-coded Doppler sonography in the examination of the renal arteries.

[The value of barium double-contrast study in the aftercare of gastrectomy patients (Roux-Y)].

We evaluated 32 patients who had undergone jejuno-oesophagostomy for gastric carcinoma. Double contrast radiography was performed 3 to 36 months after gastrectomy, 3 to 14 days prior to routine endoscopy. Endoscopy is superior to double contrast radiography in detecting tumour recurrence, particularly in small tumours, due to the possibility of biopsy.

[Strut fractures in the long-term follow-up of Günther cava filters--the results after 64 filter implantations].

Follow-up of patients with inferior vena cava filters was performed every 3 months with clinical controls, plain radiographs and duplex sonography. Whereas the clinical results were excellent (no recurrence of pulmonary embolism), radiological controls showed broken anchoring legs in 14 cases and a broken filter basket in one patient. In two cases, the broken anchoring prongs had perforated the inferior vena cava wall.

[The screening of renal artery stenoses. The initial results with the value of color Doppler sonography].

The value of colour Doppler sonography in the diagnosis of renal artery stenosis has been studied retrospectively. 17 patients were examined (34 main renal arteries and 7 accessory renal arteries; ages 37 to 84 years; 7 males and 10 females). We studied 1) ability to study the main renal arteries, 2) visibility of accessory renal arteries and 3) the sensitivity and specificity of colour Doppler sonography for the diagnosis of renal artery stenosis.
