ACR releases impact tables for 2027 MPFS proposed rule

Maximum intensity projection of Ga-68 PSMA-11 PET/CE-CT (A), Tc-99m MIP-1404 CZT SPECT/CT (B) and Tc-99m HDP CZT SPECT/CT (C) imaging. 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. Fusion axial imaging of Ga-68 PSMA-11 PET/CE-CT (D) and Tc-99m MIP-1404 CZT SPECT/CT (E) showing uptake in lymph nodes in the left pelvic area below the iliac bifurcation (arrows). Fusion axial imaging of Ga-68 PSMA-11 PET/CE-CT (F) and Tc-99m MIP-1404 CZT SPECT/CT (G) showing uptake in the right proximal femur, not detected by Tc-99m HDP CZT SPECT/CT (H), (arrows).

SPECT/CT viable over PET/CT for high-risk prostate cancer staging

Considering its broader accessibility, Tc-99m MIP-1404 CZT SPECT/CT may represent a practical alternative for primary staging.

ACR rolls out PE-RADS for pulmonary embolism care

By Amerigo Allegretto

The framework outlines grading and suggestions for CT and MRI angiography interpretation.

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.

Tau PET tracer flags early Alzheimer risk in healthy older adults

Few studies have investigated how F-18 PI-2620 is associated with memory performance or AD-related biomarkers in cognitively unimpaired older adults.

July 17, 2026

F-18 PI-2620 average binding potential maps. Mean tracer binding (DVR) image from 165 older adults (A) and 13 young adults (B). Images are scaled from 1 to 1.8 for display purposes, but DVR values of less than 1 were frequently observed.
