Radiology rallies to fight more reimbursement cuts
It's do or die for radiology as the specialty struggles to fend off proposals in the U.S. Congress mandating severe cuts in reimbursement. Radiology proponents are predicting economic Armageddon if the cuts are passed, but their arguments may not be strong enough to counter the powerful forces of healthcare reform.

Gerbode ventricular septal defect diagnosed at cardiac MR imaging: case report.
This report describes the ability of cardiac magnetic resonance (MR) imaging to depict an unusual cardiac defect. A type of ventricular septal defect called the Gerbode defect, which results in a communication between the left ventricle and the right atrium, is presented. To the authors' knowledge, this is the first time cardiac MR imaging has been utilized to characterize this defect.

Pulmonary embolism detection with dual-energy CT: experimental study of dual-source CT in rabbits.
CONCLUSION: Dual-source CT can depict normal and abnormal blood perfusion distribution in a rabbit's lung. Abnormal pulmonary blood distribution, as shown at dual-source CT, improves detection of acute PE in rabbits.

Effects of adaptive section collimation on patient radiation dose in multisection spiral CT.
CONCLUSION: Adaptive section collimation allows substantial reduction of unnecessary exposure owing to z-overscanning in spiral CT. It can be combined in synergy with other means of dose reduction, such as spectral optimization and automatic exposure control.

Rotator cuff calcific tendonitis: short-term and 10-year outcomes after two-needle us-guided percutaneous treatment--nonrandomized controlled trial.
CONCLUSION: US-guided percutaneous treatment facilitated prompt shoulder function recovery and pain relief. Treated patients had better outcomes than did nontreated patients at 1 year. However, 5 and 10 years after the procedure, the nontreated group reported outcomes similar to those of the treated group.

Feasibility of ex vivo FDG PET of the colon.
Authors: Gollub MJ, Akhurst TJ, Williamson MJ, Shia J, Humm JL, Wong WD, Paty PB, Guillem JG, Weiser MR, Temple LK, Dauer LT, Jhanwar SC, Kronman RE, Montalvo CV, Miller AR, Larson SM, Margulis AR
To facilitate future direct correlations between fluorine 18 fluorodeoxyglucose (FDG)-avid colonic lesions and immunohistochemical assay findings, the authors tested the feasibility of ex vivo FDG positron emission tomography (PET) of the colon resected from humans. In this institutional review board-approved, HIPAA-compliant study, the authors, after obtaining informed patient consent, injected FDG intraoperatively in five patients with neoplasms and imaged their resected colons approximately 3 hours later. The colon could be imaged during this fairly limited time interval, and polyps and ca......

Urethrography in men: conventional technique versus clamp method.
CONCLUSION: The conventional balloon method of performing RUG is painful and, in some cases, not effective. The clamp method is a simple, well-tolerated procedure that allowed diagnostic evaluation in all cases. Drip infusion enables RUG and VCUG to be performed without the need for syringes or bladder catheters, thus increasing patient comfort.

Evaluating variability in tumor measurements from same-day repeat CT scans of patients with non-small cell lung cancer.
CONCLUSION: Chest CT scans are well reproducible. Changes in unidimensional lesion size of 8% or greater exceed the measurement variability of the computer method and can be considered significant when estimating the outcome of therapy in a patient.
