F-fluorothymidine PET for predicting survival in patients with resectable pancreatic cancer.

Purpose: The aim of this study was to correlate preoperative 3'-deoxy-3'-[F] fluorothymidine (FLT) uptake with the clinical outcome and survival in these patients after surgery.

Materials And Methods: We performed a prospective analysis in 27 patients with adenocarcinoma of the pancreas (15 males, 12 females, mean age: 62 ± 13 years, range: 34 - 86 years). FLT PET (45 min p.

11C-choline PET/CT and whole-body MRI including diffusion-weighted imaging for patients with recurrent prostate cancer.

Purpose: To compare the detection efficacy of 11C-choline positron emission tomography and computed tomography (PET/CT) with whole-body magnetic resonance imaging (MRI) including diffusion-weighted imaging (DWI) in patients with suspected recurrent prostate cancer.

Materials And Methods: Fifty-seven patients (mean age 68, range 54-80 years) underwent 11C-choline PET/CT and MRI using T1-weighted (T1w), short-tau inversion recovery (STIR), and DWI. Two readers visually rated suspicious lesions on a 5-point scale in 20 different regions.

99mTc-DPD SPECT/CT for localisation of inflammatory and chronic osteoarthritis of the foot and ankle. Comparison with planar imaging and SPECT as a clinical adjunct in radiosynovectomy.

Aim: The precise localisation of osteoarthritic and inflammatory changes is crucial for selective treatment planning of radiosynovectomy (RSV). The present study evaluated the diagnostic accuracy of planar bone imaging and SPECT for the detection of pathological bone metabolism and inflammation in joints of the foot and ankle, compared with SPECT/CT.

Patients, Methods: 39 patients (mean age 65.

Non-invasive imaging of implanted peritoneal carcinomatosis in mice using PET and bioluminescence imaging.

Background: Non-invasive imaging of peritoneal carcinomatosis remains challenging. The aim of this study was to compare positron emission tomography (PET) and bioluminescence imaging (BLI) for the early detection of peritoneal carcinomatosis in a mouse model.

Methods: Female nude mice were inoculated intraperitoneally with 1×10(7) HSC45-M2-luc gastric cancer cells.

A comparative study of collimation in bedside chest radiography for preterm infants in two teaching hospitals.

Objective: Unnecessary exposure of the abdomen, arms or head may lead to a substantial increase of the radiation dose in portable chest X-rays on the neonatal intensive care unit. The objective was to identify potential factors influencing inappropriate exposure of non-thoracic structures in two teaching hospitals.

Methods: The study analysed 200 consecutive digital chest radiographs in 20 preterm neonates (mean gestation 25 ± 1 weeks).
