CT, MRI helps pinpoint rare pancreatic alteration cystic fibrosis patients
VIENNA - Children with cystic fibrosis may suffer from an unusual form of pancreatic alteration characterized by macrocysts of different sizes distributed all over the gland. Researchers from the department of pediatric surgery at Children’s Hospital La Paz in Madrid analyzed the radiologic features of pancreatic cysts in a study presented at the European Congress of Radiology on Monday.

MRI and SPECT garner high marks for glioma grading
VIENNA - In a comparison of gadolinium contrast-enhanced MRI and 123I-IMT SPECT for the preoperative grading of malignant gliomas, MRI fared slightly better, but both modalities proved efficient for noninvasive imaging.

Neurosurgical intervention benefits from efficient real-time fMRI planning
VIENNA - With a post-processing time of 11 minutes, functional MRI (fMRI) is a reliable, time-saving way to plan neurosurgical intervention, said radiologists from the University of Leipzig in Germany.

Full-field digital mammography holds its own against screen-film mammography
VIENNA - German researchers are bolstering the cause of full-field digital mammography (FFDM), reporting good image quality and lesion detectability in 100 patients who were screened with digital as well as screen-film mammography (SFM). Dr. Silvia Obenauer presented the results of her group’s study at the European Congress of Radiology meeting on Saturday.

Radiologists should review checklist before off-label MR contrast use
VIENNA - Peer-reviewed literature and a clear medical indication are just two of the issues that physicians should consider when deciding whether to use an MRI contrast agent for off-label purposes, according to radiologists from the German Cancer Research Center in Heidelberg and the U.S. National Institutes of Health.

Scintimammography may back up x-ray mammo better than US
Evidence continues to mount in support of scintimammography (SMM) as a second-line test for detecting potential breast cancer. The latest study out of the United Kingdom shows that SMM, when combined with traditional mammography, can improve diagnostic accuracy.

fMRI catches breast lesions early in menstrual cycle
In order to avoid missed breast lesions, functional MRI should be performed when the extraction-flow volume is at its lowest in a woman’s menstrual cycle, according to researchers from Massachusetts General Hospital in Boston.

Dynamic PET/CT and pathologic images for a 66-year-old male participant. (A) Axial dynamic PET/CT image acquired during intravenous administration of Ga-68 PSMA-11 demonstrates the hypermetabolic primary prostatic tumor. The right-sided portion of the lesion used for volume of interest (VOI) analysis is outlined in pink, reflecting the margins seen on a prior T2-weighted MRI scan. Tumor radiotracer uptake extends across midline into the left anterior apex (*). (B) Axial dynamic PET/CT image acquired during selective right prostatic arterial administration of Ga-68 PSMA-11 demonstrates intense radiotracer uptake in the VOI outlined in pink. There is comparatively minimal uptake in the unperfused left-sided portion of the tumor (*). The arterial sheath and catheters in the right groin are partially visualized (arrow). (C) Photomicrograph (hematoxylin-eosin stain; unmagnified) of the prostatic apex after radical prostatectomy. The midline (dotted line) and dominant tumor margins (solid line) are shown. Small additional areas of carcinoma (■) without T2-weighted MRI correlates were also identified at pathologic examination.
