Ga-68 PSMA-11 PET/CE-CT and Tc-99m MIP-1404 CZT SPECT/CT showing tracer uptake in lymph nodes below the iliac bifurcation and above, paraaortic and left supraclavicular, bone uptake in the right proximal femur and right scapula (arrows). Tc-99m HDP CZT SPECT/CT did not show any uptake suspicious for metastatic disease. No sclerotic lesions suspicious of metastases were detected by the CT component in any of the studies.

ACR rolls out PE-RADS for pulmonary embolism care
By Amerigo Allegretto

July 21, 2026
Acute pulmonary embolism (PE) with right ventricle (RV) enlargement and clot-in-transit. PE chest axial CT angiography images demonstrate pulmonary embolus in the right pulmonary artery (white solid arrow), an enlarged RV (dotted arrow), and thrombus transiting through the right atrium (black arrows), PE-RADS 4/RV+/T+. The “4” refers to the PE‑RADS ordinal category for the most proximal clot location (central arteries). “RV+” indicates RV enlargement (RV to left ventricle ratio ≥ 1.0). “T+” indicates definitive thrombus identified in the right atrium and/or RV.
