CADx outperforms radiologists in characterizing liver lesions
By Erik L. Ridley
Monday, November 26 | 10:50 a.m.-11:00 a.m. | SSC08-03 | Room S402ABResearchers in Germany have found -- with a caveat -- that a computer-aided diagnosis (CADx) system turned in a better performance than radiologists for characterizing indeterminate liver lesions.

PET/MRI tops PET/CT in abdominopelvic lesion conspicuity
By Wayne Forrest
Wednesday, November 28 | 11:50 a.m.-12:00 p.m. | SSK08-09 | Room S504CDPET/MRI with ultrafast gradient-recalled echo and spin-echo sequences is superior to PET/CT for lesion conspicuity, thus potentially improving therapy for patients with abdominopelvic cancer, according to a study by Swiss researchers.

FDG-PET/CT helps assess pancreatic cancer recurrence
By Wayne Forrest
Wednesday, November 28 | 11:30 a.m.-11:40 a.m. | SSK13-07 | Room S505ABFDG-PET/CT has "excellent accuracy" in detecting a recurrence following resection of pancreatic cancer, and maximum standardized uptake values can be used in determining the prognosis of these patients, according to researchers from India.

DOTATATE-PET/CT helps detect pancreatic neuroendocrine tumors
By Wayne Forrest
Monday, November 26 | 11:50 a.m.-12:00 p.m. | SSC13-09 | Room 505ABIn this retrospective study from University of Munich Hospital, researchers found that DOTATATE-PET/CT detects pancreatic neuroendocrine tumors better than MRI.

Microbubble US helps early assessment of liver dysplasia
By Wayne Forrest
Monday, November 26 | 11:30 a.m.-11:40 a.m. | SSC09-07 | Room S504CDIn this presentation, German researchers will discuss their preliminary success with an ultrasound contrast agent -- known as BR55 -- that uses microbubbles targeting vascular endothelial growth factor receptor 2 to assess liver dysplasia.

PET/MRI outshines PET/CT in lesion detection
By Wayne Forrest
Monday, November 26 | 11:00 a.m.-11:10 a.m. | SSC13-04 | Room S505ABPET/MRI showed superior lesion detectability compared to contrast-enhanced PET/CT in this study from King Fahad Specialist Hospital in Dammam, Saudi Arabia. Based on the results, researchers concluded that PET/MRI may be useful for abdominal lesion staging while sparing patients from contrast media.

Elastography offers noninvasive assessment of liver fibrosis
By Kate Madden Yee
Monday, November 26 | 8:55 a.m.-9:05 a.m. | VSGI21-02 | Room N227Steatosis does not affect shear-wave elastography estimation of liver fibrosis -- but inflammation does, according to a presentation to be given on Monday by researchers from Massachusetts General Hospital.

CEUS comparable to MDCT for managing colorectal cancer patients
By Kate Madden Yee
Sunday, November 25 | 12:30 p.m.-1:00 p.m. | LL-GIS-SU2A | Lakeside Learning CenterContrast-enhanced ultrasound (CEUS) is comparable to MDCT in assessing patients undergoing antiangiogenic drug-based neoadjuvant therapy for colorectal cancer liver metastasis, according researchers from Italy.

Single-phase CT of the liver sufficient for melanoma surveillance
By Eric Barnes
Friday, November 30 | 11:10 a.m.-11:20 a.m. | SST05-05 | Room E353CSingle portal-venous phase CT is adequate for hepatic metastatic disease surveillance in patients with metastatic cutaneous melanoma, concluded researchers from Utah, who found that arterial-phase CT didn't provide much additional information.

Flat-panel CT perfusion monitors hepatic blood volume in real-time
By Eric Barnes
Thursday, November 29 | 11:20 a.m.-11:30 a.m. | SSQ19-06 | Room N227Flat-panel CT can monitor hepatic blood-volume changes right in the angiographic suite with the patient on the table, which could be useful during transarterial chemoembolization procedures, according to researchers from Shanghai Jiao Tong University in China.
