DOTATOC-PET/CT appears better at sarcoidosis lesion detection

By Wayne Forrest

Tuesday, December 2 | 3:10 p.m.-3:20 p.m. | SSJ20-02 | Room S505ABResearchers were able to detect more lesions in sarcoidosis patients using PET/CT with gallium-68 DOTATOC than conventional gallium-67 citrate scintigraphy in this study from Kyoto University in Japan.

Researchers try to take the guesswork out of sarcoidosis

By Wayne Forrest

Tuesday, December 2 | 11:10 a.m.-11:20 a.m. | SSG08-05 | Room S504CDSarcoidosis can be a difficult disease to diagnose, with FDG-PET/CT scans occasionally mistaking inflammation for cancer. To address this issue, researchers from India conducted a study that included 50 cancer patients and 14 sarcoidosis patients with no malignancy.

Study determines SUVmax cutoff for accurate solitary lung nodule prognosis

By Wayne Forrest

Monday, December 1 | 10:40 a.m.-10:50 a.m. | SSC03-02 | Room S404ABItalian researchers have determined the optimum cutoff of maximum standardized uptake value (SUVmax) for an accurate prognosis of patients with solitary lung nodules.

Cerebral angiographic data reconstructed from time-resolved CTP

Friday, December 5 | 11:50 a.m.-12:00 p.m. | SST14-09 | Room S403BWavelet analysis is a powerful method of displaying angiographic data from CT perfusion (CTP) and for separating arterial and venous flow patterns. Can it be used to visualize the vascular tree from CTP data in stroke patients, eliminating the need for a separate angiography exam routinely performed for that purpose?
