[High-resolution CT in the early and late form of lymphangioleiomyomatosis].

We report on two cases of pulmonary lymphangiomyomatosis, one of which was diagnosed by chance. Retroperitoneal lymphomas were found during a routine "check-up" and biopsy proved a lymphangiomyomatosis (LAM). High resolution CT of the lung was typical for pulmonary LAM.

[MR angiography of pelvic veins and the inferior vena cava using 0.5 tesla].

The pelvic veins and/or the inferior vena cava were examined in 15 patients with pelvic vein thrombosis or retroperitoneal tumours, using phlebography or cavography and MR angiography. The latter was carried out using 0.5 Tesla with an inflow technique TR/TE 30/8 ms, flip angle 70 degrees).

[Diagnostic imaging of abdominal trauma].

Imaging in abdominal trauma with special regard to the value of abdominal x-ray, ultrasound and computed tomography is described. The introduction to each organ focuses on the clinical situation, special mechanism of trauma, symptoms and the pathological staging of trauma.

[Modern tomographic procedures in the diagnosis of petrous bone processes].

This report reviews high resolution computed tomography of the petrous bone. The findings in acoustic neurinoma, paraganglioma and cholesteatoma are described with special regard to their differential diagnosis. Although in preoperative strategy the main focus is on computed tomography because of its exact delineation of bony structures, the article also focuses on the findings in Magnetic Resonance Imaging.

The value of bone scintigraphy, bone marrow scintigraphy and fast spin-echo magnetic resonance imaging in staging of patients with malignant solid tumours: a prospective study.

The purpose of this prospective study was to define the value of bone scintigraphy (BS), bone marrow scintigraphy (BMS) and the new fast spin-echo (FSE) magnetic resonance imaging (MRI) sequences in screening for bone metastases in patients with solid malignant tumours. It was our particular interest to classify patients into a group with and a group without bone metastases, and not only to compare the absolute number of metastases detected by each method. Thirty-two patients were examined using technetium-99m dicarboxy propane diphosphonate bone scintigraphy, 99Tc-labelled monoclonal anti-granulocyte antibodies for bone marrow scintigraphy and 1.

Bronchogenic carcinoma mimicking metastatic thyroid carcinoma.

We present a case of a false-positive 131I scan in the follow-up of a patient with papillary thyroid carcinoma, which developed 24 yr after radiation therapy for Hodgkin's disease. In the primary evaluation of a neck mass, histology was typical for a papillary thyroid carcinoma and thyroglobulin staining was positive. After total thyroidectomy, 131I uptake was seen in the hilum and right lung.

[Multimodal imaging exemplified by gluteal abscesses--a case report].

The detection of occult abscesses can draw a long chain of diagnostic procedures as the procedures as the presented case documents. Next to conventional X-ray studies and examination by ultrasound scintigraphy is available. Studies of the skeleton by the latter using phosphonates for osteomyelitis or 111-I-labeled neutrophils or 99m-Tc-labeled monoclonal antibodies against neutrophilic surface-antigens for the detection of abscesses in soft tissues are of recent interest.

[Positron-emission tomography (PET) in the evaluation of metabolic processes in the myocardium].

Nuclear cardiology, and in particular myocardial scintigraphy, is used with increasing frequency to detect the presence of ischemia before revascularization by angioplasty or coronary artery bypass grafting. On the basis of recent publications it is evident that there are certain conditions in which conventional diagnostic methods suggest the presence of myocardial necrosis, but there is persistent metabolically active myocardial tissue. One of these conditions is the "hibernating myocardium".

[Nasopharyngeal involvement in Hodgkin's disease--its diagnosis by CT and MRT. A case report].

Lymphocyte predominance subtype of M. Hodgkin with disease of the upper cervical and/or preauricular lymph nodes more often shows simultaneous involvement of nasopharynx. Epipharyngoscopy alone is not always diagnostic.
