Computed Tomography Observer Agreement in Staging Malignant Lymphoma.

Objective: To determine pretreatment computed tomography observer agreement in patients with newly diagnosed lymphoma.

Methods: Forty-nine computed tomography scans were reviewed by 3 experienced radiologists, with each scan assessed twice by 1 observer. Predefined nodal and extranodal regions were assessed, and Ann Arbor stages were assigned.

Bone suppressed images improve radiologists' detection performance for pulmonary nodules in chest radiographs.

Objectives: To assess the effect of bone suppression imaging on observer performance in detecting lung nodules in chest radiographs.

Materials And Methods: Posteroanterior (PA) and lateral digital chest radiographs of 111 (average age 65) patients with a CT proven solitary nodule (median diameter 15 mm), and 189 (average age 63) controls were read by 5 radiologists and 3 residents. Conspicuity of nodules on the radiographs was classified in obvious (n = 32), moderate (n = 32), subtle (n = 29) and very subtle (n = 18).

Bone mineral density in male adolescents with autism spectrum disorders and disruptive behavior disorder with or without antipsychotic treatment.

Objective: To investigate the long-term effects of antipsychotic (AP) treatment and AP-induced hyperprolactinemia on bone mineral density (BMD) and body composition in male adolescents with autism spectrum disorders (ASDs) and/or disruptive behavior disorder (DBD).

Design: Physically healthy 10- to 20-year-old boys with ASD and/or DBD, chronically treated (n=56; mean 52 months, range 16-126 months) or not treated (n=47) with an AP, were recruited to this observational study. Prolactin levels and biochemical bone parameters were measured and BMD of the lumbar spine and total body, and body composition were assessed by dual-energy X-ray absorptiometry, and volumetric BMD of the lumbar spine calculated.

Diagnostic evaluation of separately acquired PET and CT images by nuclear medicine physicians and radiologists in cancer patients.

The aim of our study was to analyze how many oncology patients might benefit from a) integrated positron emission tomography - multidetector computed tomography (PET/MDCT) and additionally b) clinically relevant information provided by either the CT scan or PET scan. A total of 285 consecutive patients 164 male and 121 female, age range 17-84 years, 153 lung cancer, 112 lymphoma, 20 miscellaneous, referred for PET and separate CT scan, were included. The CT scan was performed after the intravenous injection of a soluble contrast media.
