Randomized Controlled Trial Multicenter StudyCT and PET: early prognostic indicators of response to imatinib mesylate in patients with gastrointestinal stromal tumor.
We report results from a pilot study aimed at optimizing the use of CT bidimensional measurements and 18F-FDG PET maximum standardized uptake values (SUVs-(max)) for determining response to prolonged imatinib mesylate treatment in patients with advanced gastrointestinal stromal tumors (GISTs). ⋯ The two best metrics were the optimized PET SUVmax threshold of 3.4 at 1 month (p = 0.00002) and the optimized CT bidimensional measurement threshold (no growth from baseline to 1 month, p = 0.00005) in this patient group.

Clinical TrialRelationship between cement distribution pattern and new compression fracture after percutaneous vertebroplasty.
The objective of this study was to prospectively investigate relationships between cement distribution patterns and the occurrence rates of new compression fractures after percutaneous vertebroplasty. ⋯ Although cement distribution patterns do not significantly affect initial clinical response, a higher incidence of new compression fractures is seen in patients with treated vertebrae exhibiting a cleft pattern.

ReviewPostoperative imaging in cyanotic congenital heart diseases: part 2, Complications.
The purpose of this article is to illustrate the MRI appearance of postoperative complications in the surgical procedures most commonly performed to correct cyanotic congenital heart disease. ⋯ The radiologist must be familiar with the morphologic and functional MRI appearances of surgical complications in patients with palliated or repaired cyanotic congenital heart disease to deliver an accurate diagnosis on which to base management decisions.

ReviewPostoperative imaging in cyanotic congenital heart diseases: part 1, Normal findings.
The objective of this article is to illustrate the most common surgical procedures performed in patients with cyanotic congenital heart diseases along with the respective postoperative MRI findings normally seen in clinical practice. ⋯ Radiologists need a solid knowledge of the surgical procedures used to treat patients with cyanotic congenital heart diseases to identify what constitutes normal postoperative findings on MR images and to play an ongoing role in the integral lifelong care of these patients.

Comparative Study Controlled Clinical TrialOptimization of selection for nonoperative management of blunt splenic injury: comparison of MDCT grading systems.
The purpose of this study was to compare the usefulness of two CT grading systems of blunt splenic trauma in predicting which patients need surgery or angioembolization. ⋯ The proposed CT grading system is better than the AAST system for predicting which patients with blunt splenic trauma need arteriography or splenic intervention.
