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.

Study pinpoints optimal ASIR blend for stomach cancer
By Eric Barnes
Wednesday, November 28 | 3:40 p.m.-3:50 p.m. | SSM08-05 | Room E353BWhat's the best blend of adaptive statistical iterative reconstruction (ASIR) for evaluating gastric cancers for postoperative follow-up? Researchers from South Korea wanted to minimize radiation dose but avoid missing a recurrence, so they systematically analyzed the results of different blends.

Multienergy CT improves virtual colonoscopy CAD performance
By Eric Barnes
Tuesday, November 27 | 3:50 p.m.-4:00 p.m. | SSJ08-06 | Room E353CMultienergy CT can boost the detection accuracy of computer-aided detection (CAD) in virtual colonoscopy because it provides more information about the chemical composition of materials in the colon than conventional CT, according to researchers from Massachusetts General Hospital.

Supine-prone registration for CT colonography taps marginal artery
By Eric Barnes
Tuesday, November 27 | 3:10 p.m.-3:20 p.m. | SSJ08-02 | Room E353CUse of the marginal artery for registration of supine and prone CT colonography datasets may permit more efficient data registration and improve diagnostic accuracy, say researchers from the U.S. National Institutes of Health.

Split-bolus spectral CT halves pancreas dose, boosts conspicuity
By Eric Barnes
Tuesday, November 27 | 11:50 a.m.-12:00 p.m. | SSG07-09 | Room E353CCT split-bolus spectral CT improves vascular, liver, and pancreatic attenuation and tumor conspicuity in the pancreas compared with two-phase imaging, using half the radiation dose, say researchers from Beth Israel Deaconess Medical Center.

Spectral CT can differentiate gastric carcinoma
By Eric Barnes
Tuesday, November 27 | 10:50 a.m.-11:00 a.m. | SSG16-03 | Room S403BSpectral CT can be used to distinguish moderately differentiated adenocarcinoma from poorly differentiated adenocarcinoma and is helpful for evaluating the differentiation state of gastric cancers, say researchers from China.

Tweaking criteria fine-tunes definition of resectable pancreatic cancer
By Eric Barnes
Tuesday, November 27 | 10:30 a.m.-10:40 a.m. | SSG07-01 | Room E353CDecision-making in borderline resectable pancreatic cancers may benefit from refinement of the preoperative CT criteria for venous involvement, concluded researchers from Tata Memorial Centre in Mumbai, India.

MBIR tops ASIR for ultralow-dose CT enterography
By Eric Barnes
Monday, November 26 | 11:00 a.m.-11:10 a.m. | SSC05-04 | Room E353ARadiation doses from CT enterography can be dramatically reduced with the use of iterative reconstruction. Find out how model-based iterative reconstruction (MBIR) came out on top in this Monday scientific session.
