Could Ga-68 PSMA PET become essential for prostate cancer?

April 23, 2019 -- Coupling the radiopharmaceutical gallium-68 (Ga-68) prostate-specific membrane antigen (PSMA) with PET/CT or PET/MRI has been a boon for prostate cancer imaging. But clinicians still need to be aware of some inherent shortcomings with the radiopharmaceutical, according to a research review published online April 12 in Urology. Discuss

5 steps for putting abbreviated MRI into your practice

April 23, 2019 -- Breast MRI is the most sensitive tool for detecting breast cancer, but its cost and time requirements often hinder its use, according to a new study published April 17 in the American Journal of Roentgenology. Yet with the development of an abbreviated MRI protocol, the modality is becoming an increasingly viable option. Discuss
