MR venography using time-resolved imaging in interventional management of pelvic venous insufficiency.

Purpose Of Review: To evaluate the utility of magnetic resonance venography with time-resolved imaging (MRV TRI) in the diagnosis of pelvic vein insufficiency (PVI).

Recent Findings: A retrospective single-center review of N = 17 consecutive patients who underwent pelvic MRI for the assessment of PVI was performed. N = 8/17 (47%) studies were positive for PVI.

Splenic sarcoidosis: a case report and review of the imaging findings of multiple incidental splenic lesions as the initial presentation of sarcoidosis.

MRI is helpful in characterizing splenic lesions, but there can be significant variability and overlap in the appearance of both benign and malignant splenic lesions; thus, a confident diagnosis can be presentation and classic imaging appearance , and further assessment for any other associated findings suggestive of systemic sarcoidosis is critical to avoid missed or delayed diagnosis-specifically, to avoid over-diagnosis of malignant disease because multiple splenic lesions can be the initial presentation of sarcoidosis.

Needle thoracostomy in the treatment of a tension pneumothorax in trauma patients: what size needle?

Background: A tension pneumothorax requires immediate decompression using a needle thoracostomy. According to advanced trauma life support guidelines this procedure is performed in the second intercostal space (ICS) in the midclavicular line (MCL), using a 4.5-cm (2-inch) catheter (5-cm needle).

Portal vein thrombi after ileal pouch-anal anastomosis: its incidence and association with pouchitis.

Purpose: Portal vein thrombi (PVT) have recently been linked to ileal pouch-anal anastomosis (IPAA). We assessed the rate of PVT in patients who underwent IPAA and attempted to identify the associated features.

Methods: We reviewed all patients who underwent IPAA at our hospital between 1997 and 2002, noting demographic, operative, and clinical data.

Prostate cancer: gadolinium-enhanced MR imaging at 3 weeks compared with needle biopsy at 6 months after cryoablation.

Purpose: To determine if nonenhancing tissue on gadolinium-enhanced magnetic resonance (MR) images obtained 3 weeks after cryoablation of the prostate helps reliably and accurately predict nonviable cryoablated tissue at 6-month biopsy.

Materials And Methods: Fifty-four consecutive patients with prostate cancer who underwent cryoablation were followed up prospectively. Fifty-one underwent gadolinium-enhanced MR imaging at 3 weeks (three had gadolinium allergy); 49, biopsy at 6 months (three refused and two had other primary malignancies); and all, prostate-specific antigen (PSA) tests at 6 weeks, 3 months, and every 3 months thereafter.
