Novel Radiotracer Demonstrates High Diagnostic Efficacy for Obese Patients with Coronary Artery Disease

Imaging Technology

18F-flurpiridaz PET MPI obtained images at a lower radiation dose than 99Tc-SPECT MPI and performed similarly in both obese and non-obese patients. 18F-flurpiridaz PET MPI had a sensitivity of 77 percent and a specificity of 67 percent in diagnosing significant CAD, while 99mTC-SPECT MPI had a sensitivity of 69.2

Dual-tracer PET/CT shows promise in liver cancer patients

AuntMinnie

A group led by researchers at the University of Hong Kong in China found the approach detected 12% more disease in patients undergoing staging than CT or MRI and resulted in a change in treatment in a significant number of cases. The results validate the emerging technique, the group noted. In addition, it identified new lesions in 14.3%

SNMMI: FAPI PET/CT predicts progressive pulmonary fibrosis better than FDG

AuntMinnie

Fibroblast activation protein inhibitor (FAPI) PET/CT demonstrated heightened and extensive uptake in interstitial lung disease (ILD) compared to FDG in a cohort of 97 patients with ILD. To evaluate the value of FAPI PET/CT versus FDG in ILD diagnoses, Fang and colleagues conducted both within one week and assessed various PET/CT parameters.

Deep Learning-assisted Lesion Segmentation in PET/CT Imaging: A Feasibility Study for Salvage Radiation Therapy in Prostate Cancer

Imaging Technology

Prostate cancer persists as the most frequently diagnosed malignancy in men beyond skin cancer. To design the salvage radiation therapy, imaging is required to detect and locate the recurrence disease regime.” In this new editorial, researchers Richard L.J.
