Muscle MRI in McArdle Disease: A European Multicenter Observational Study.

Background And Objectives: Glycogen storage disease type V (GSDV) or McArdle disease is a muscle glycogenosis that classically manifests with exercise intolerance and exercise-induced muscle pain. Muscle weakness and wasting may occur, but it is typically mild and described as located around the shoulder girdle in elderly patients. Paraspinal muscle involvement has received little attention in the literature.

Negative predictive value for cancer in patients with "gray-zone" PSA level and prior negative biopsy: preliminary results with multiparametric 3.0 Tesla MR.

Purpose: To investigate the negative predictive value (NPV) for malignancy of 3.0 Tesla (T) MRI in patients with "gray zone" PSA level and prior negative biopsies.

Materials And Methods: We enrolled 26 patients with PSA level between 2.

Residual prostatic tumour in the surgical bed following radical prostatectomy in organ-confined prostate cancer: possible prognostic significance.

Introduction And Objectives: The aim of our study was to verify the impact of benign and malignant residual glandular tissue on surgical bed after radical prostatectomy, in terms of both biochemical and clinical disease progression, in a group of patients with pathologically organ-confined cancer of the prostate (PCa).

Material And Methods: Files from 70 consecutive patients who undergone radical retropubic prostatectomy (RRP) for organ-confined PCa were retrospectively evaluated. During each intervention, after prostate removal, biopsies of the surgical bed were obtained from the following sites: urethral/periapical section margin, basal, left and right postero-lateral and under/retrotrigonal regions.

Borderline breast lesions: comparison of malignancy underestimation rates with 14-gauge core needle biopsy versus 11-gauge vacuum-assisted device.

Objective: To compare malignancy underestimation rates in the case of percutaneous diagnosis of borderline breast lesions(B3) at 14-g core-needle-biopsy (CNB) and at 11-g vacuum-assisted-biopsy (VAB).

Methods: The histological results of 4764 image-guided breast biopsies were retrospectively reviewed. 300 B3, 151 benign papillomas, 88 radial sclerosing lesions, 46 lobular neoplasia, 15 atypical ductal hyperplasia diagnosed at ultrasound-guided 14-g CNB (76%) or stereotactically-guided 11-g VAB (24%) were identified.

Incidental pancreatic cysts on 3D turbo spin echo magnetic resonance cholangiopancreatography: prevalence and relation with clinical and imaging features.

Purpose: To estimate the prevalence of incidental pancreatic cysts (IPCs) in asymptomatic patients addressed to magnetic resonance cholangiopancreatography (MRCP), and to correlate it with clinical and imaging features.

Materials And Methods: Magnetic resonance cholangiopancreatography performed over 26-months on 152 patients with unsuspected/unknown pancreatic disease were reviewed to assess IPCs' features of presentation. Multivariate analysis was performed to evaluate the correlation of IPCs with clinical information and type of pancreaticobiliary findings at MRCP.

Unusual malignant tumors of the breast: MRI features and pathologic correlation.

Unusual malignant breast tumors are well-differentiated subtypes of invasive ductal carcinoma, including mucinous, tubular, medullary and papillary carcinomas, and account for about 10% of malignant breast tumors. They are increasingly being encountered during magnetic resonance imaging (MRI) examinations of the breast. Therefore, breast radiologists should be aware of their appearance on MRI.

MRI scoring system including dynamic motility evaluation in assessing the activity of Crohn's disease of the terminal ileum.

Rationale And Objectives: We sought to investigate the value of a MRI scoring system including dynamic motility evaluation in the assessment of small bowel Crohn's disease activity.

Materials And Methods: From March 2005 to December 2006, 52 patients with suspected Crohn's disease onset or relapse underwent MRI on a 1.5-T magnet.
