Whole-body diffusion-weighted magnetic resonance imaging at 3 Tesla for early assessment of treatment response in non-Hodgkin lymphoma: a pilot study.

Objective: To evaluate 3 Tesla (T) whole-body diffusion-weighted magnetic resonance imaging (WB DWI) for early treatment assessment in aggressive non-Hodgkin lymphoma (NHL).

Methods: Fourteen patients with NHL treated with standard chemotherapy underwent 3-T WB DWI before and 2 and 4 weeks during treatment, using b-values of 0-1000 s/mm(2) from which the apparent diffusion coefficient (ADC) was calculated. Patient follow-up (average 20.

Magnetic resonance imaging: value of diffusion-weighted imaging in differentiating benign from malignant breast lesions.

Objectives: Although magnetic resonance imaging (MRI) has a high sensitivity in the detection of tumours, there is still much discussion about its role in breast cancer detection. MRI is not yet routinely used to further characterize lesions in patients diagnosed with breast cancer. This study investigated the impact of preoperative MRI on the surgical treatment of women with biopsy proven breast cancer.

Life-threatening lower gastrointestinal bleeding in a 2-year-old boy treated by transcatheter embolization: uncommon features of a complicated Meckel diverticulum.

A 2.5-year-old boy presented with life-threatening lower gastrointestinal (GI) bleeding. Radiological investigation, including US, CT and 99 m-Technetium (Tc) pertechnate scintigraphy, was negative.

Detection of non-ST-elevation myocardial infarction and unstable angina in the acute setting: meta-analysis of diagnostic performance of multi-detector computed tomographic angiography.

Background: Multi-detector computed tomography angiography (MDCTA) has been increasingly used in the evaluation of the coronary arteries. The purpose of this study was to review the literature on the diagnostic performance of MDCTA in the acute setting, for the detection of non-ST-elevation myocardial infarction (NSTEMI) and unstable angina pectoris (UAP).

Methods: A Pubmed and manual search of the literature published between January 2000 and June 2007 was performed.

Case report: a gossypiboma in the shoulder.

We present the case of a 15-year-old boy who underwent shoulder surgery for repair of a Bankart lesion after dislocation of his right shoulder. A compress was left in the surgical wound. This case is presented to highlight an important pitfall in the diagnosis of gossypiboma (foreign body reaction): when the wires of a compress are visualized on X-ray, beware of the fact that it is possibly located inside the body.
