Cardiotoxicity as important differential diagnosis for reduced myocardial blood flow during Rubidium cardiac PET/CT : Cardiotoxicity in Rubidium PET/CT.

A 65-year-old woman with a history of ductal mammary carcinoma and recent autonomic dysfunction underwent a Rb-82 chloride (RbCl) cardiac PET/CT scan that showed no ischemia or scarring, but significantly reduced myocardial flow reserve (MFR) (global: 1.5) and a CAC-Score of 0. The patient's chemotherapy history (paclitaxel, carboplatin, epirubicin, pembrolizumab 2 years before) with elevated Troponin T and NT-pro-BNP levels at that time, and now reduced MFR with 0 CAC suggests cancer-therapy-related cardiotoxicity.

How Prostate Cancer Growth Patterns Impact Detection and Interreader Agreement on Multiparametric MRI.

Rationale And Objectives: Multiparametric MRI (mpMRI) substantially improves the detection of significant prostate carcinoma (PCa) compared to systematic biopsy. Nevertheless, mpMRI can overlook aggressive forms of PCa. Recent studies showed, that infiltrative growth (INF) has less restricted diffusion.
