Biparametric MRI of the prostate.

Biparametric Magnetic Resonance Imaging (bpMRI) of the prostate combining both morphologic T2-weighted imaging (T2WI) and diffusion-weighted imaging (DWI) is emerging as an alternative to multiparametric MRI (mpMRI) to detect, to localize and to guide prostatic targeted biopsy in patients with suspicious prostate cancer (PCa). BpMRI overcomes some limitations of mpMRI such as the costs, the time required to perform the study, the use of gadolinium-based contrast agents and the lack of a guidance for management of score 3 lesions equivocal for significant PCa. In our experience the optimal and similar clinical results of the bpMRI in comparison to mpMRI are essentially related to the DWI that we consider the dominant sequence for detection suspicious PCa both in transition and in peripheral zone.

Is contrast enhancement needed for diagnostic prostate MRI?

Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) provides clinical guidelines for multiparametric magnetic resonance imaging (mpMRI) [T2-weighted imaging (T2WI), diffusion-weighted imaging (DWI) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI)] of prostate. However, DCE-MRI seems to show a limited contribution in prostate cancer (PCa) detection and management. In our experience, DCE-MRI, did not show significant change in diagnostic performance in addition to DWI and T2WI [biparametric MRI (bpMRI)] which represent the predominant sequences to detect suspected lesions in peripheral and transitional zone (TZ).

Biparametric Multiparametric MRI with Non-endorectal Coil at 3T in the Detection and Localization of Prostate Cancer.

Aim: To assess the sensitivity of biparametric magnetic resonance imaging (bpMRI) with non-endorectal coil in the detection and localization of index (dominant) and non-index lesions in patients suspected of having prostate cancer.

Patients And Methods: We carried-out a retrospective analysis of multiparametric MRI (mpMRI) of 41 patients who underwent radical prostatectomy. Results of MRI for detection and localization of index and non-index lesions were correlated with those of histology.

Contrast enhanced ultrasound (CEUS) in blunt abdominal trauma.

In the assessment of polytrauma patient, an accurate diagnostic study protocol with high sensitivity and specificity is necessary. Computed Tomography (CT) is the standard reference in the emergency for evaluating the patients with abdominal trauma. Ultrasonography (US) has a high sensitivity in detecting free fluid in the peritoneum, but it does not show as much sensitivity for traumatic parenchymal lesions.

Nonmyxoid mediastinal lipoblastoma in a 2-year-old girl: Case report with US, CT, and MRI findings.

Lipoblastomas are rare, benign tumors of mesenchymal origin that contain adipose tissue. They usually develop in the soft tissues of an extremity in infants, children, and young adolescents. We report the case of a 22-month old girl referred to our staff for swelling in the supraclavicular fossa, which was observed when the child cried.

MRI accuracy in residual disease evaluation in breast cancer patients treated with neoadjuvant chemotherapy.

Aim: To assess the accuracy of magnetic resonance imaging (MRI) in evaluating residual disease after neoadjuvant chemotherapy in patients with large breast cancers.

Materials And Methods: Forty-five women with large breast cancers underwent MRI mammography before and after neoadjuvant chemotherapy (three or six cycles). Dynamic MRI was performed using a 1.

A case of intracystic breast cancer.

The case of a 70-year-old female patient with family history of breast cancer come to the breast Unit for the presence of a nodular swelling in the right breast is discussed. On mammography and US a gross cystic neoformation with vascularized mural nodes was identified. Another contralateral solid nodular neoformation suggestive of malignancy was also present.

Combined diagnostic imaging and management of a breast tumor in a young woman.

The typical presentation of breast cancer in a young woman is discussed. Diagnostic imaging of the breast showed the presence of an extensive pathological area, approximately 5 cm in size, at the level of the upper quadrants of left breast. On mammography the pathological sign was represented by numerous regional granular microcalcifications.

Anterior shoulder dislocation and injuries of the rotator cuff in patients aged over 40 years. Clinical and sonographic study.

A total of 39 patients with a mean age of 64 years (41 to 88) who had had anterior shoulder dislocation were followed-up an average of 2 years after trauma in order to evaluate the conditions of the rotator cuff. All of the patients were evaluated clinically, radiographically, and sonographically. Clinical evaluation revealed significant differences between the dislocated shoulders and the contralateral ones: the mean Constant score was 67 in the group with dislocated shoulders and 87 in the contralateral group.

[Percutaneous alcohol injection in hyperparathyroidism. Experience in 11 cases with an 18-month follow-up].

The authors report the results of US-guided percutaneous ethanol injection into parathyroid glands of 11 patients with primary (2) and secondary (9) hyperparathyroidism. Selection criteria for choosing ethanol treatment were the patient's refuse of surgery and high surgical risks for age or severe chronic intercurrent conditions. At 18 months' follow-up, PTH serum levels had normalized in 2 primary and 2 secondary hyperparathyroidism patients; in all the others but one, PTH levels markedly decreased--always > 50% relative to pretreatment values.

[Echography and integrated imaging in the diagnosis of hyperparathyroidism].

The authors report their personal experience with US, CT, biopsy and, lately, MRI, to localize enlarged parathyroid glands in primary and secondary hyperparathyroidism. December 1986 through December 1993, sixty-four primary and 55 secondary hyperparathyroidism patients were examined--119 in all. At biopsy and surgery, US sensitivity appeared to be 72%, with 0.

Surveillance and treatment of liver transplant recipients for candidiasis and aspergillosis.

Between June 1988 and May 1991 88 orthotopic liver transplants and 1 liver and pancreas transplant were performed at the Liver Transplantation Department of the Ospedale Maggiore of Milan. All the patients underwent mycological surveillance and received antifungal prophylaxis with oral amphotericin B (6000 mg/day) or oral or intravenous fluconazole (200 mg/day) from the time of their transplant. The incidence of Candida colonization was 67%.

[The advantages of combined US-fluoroscopic guidance in the drainage of abdominal abscesses].

The authors report their experience with 19 percutaneous drainages of abdominal abscesses in 19 patients. Six collections were in the subphrenic spaces, 6 in the liver, 1 in the infracolic space, 2 in the psoas muscle, 3 within the abdominal wall, and 1 in the pararenal space. Their etiology was abdominal surgery in 10 patients, biliary obstruction in 1, and trauma in 2; in the extant patients a hematogenous infection was supposed.

[A case of teratoma of the urachus].

The paper reports a case of teratoma of the urachus in a 53-year-old patient. The difficulties of diagnosing this pathology are underlined, in particular in relation to the rarity of the site of which no other examples have been reported in the literature.
