SNMMI: Machine-learning model predicts RPT dose
Dosimetry plays a central role in optimizing lutetium-177 (Lu-177) PSMA therapy, yet calculating it currently depends on post-therapy imaging.

SNMMI: Text confirmations cut PET/CT cancellations by 73.5%
Common causes of appointment cancellations include patient no-shows, same-day cancellations for personal reasons, non-compliance with pre-procedural instructions, and abnormal blood glucose.

Kiara Schmidt of Froedtert Health presented a study May 30 at the SNMMI annual meeting.

CT collateral status may predict outcomes in stroke patients
The findings have implications for future research to determine which stroke patients with medium-vessel occlusion benefit from EVT.
May 26, 2026
Exemplary cases from the ESCAPE-MeVO trial illustrating good, moderate, and poor collateral status at baseline multiphase CT angiography (CTA). (A) Sagittal image shows a left anterior middle cerebral artery medium-vessel occlusion (MeVO) with a calcified thrombus (arrow). (B–D) Axial images show the (B) arterial, (C) peak venous, and (D) delayed venous phases of the baseline multiphase CTA examination. The affected brain parenchyma is highlighted by the dashed outline. The collateral status is good, with early filling of more than 50% of the leptomeningeal collaterals compared with the contralateral side in the arterial phase (B), and there is no delayed washout in the peak venous (C) or delayed venous phase (D). (E) Sagittal image shows a left anterior middle cerebral artery MeVO (arrow). (F–H) Axial images show the (F) arterial, (G) peak venous, and (H) delayed venous phases of the baseline multiphase CTA examination. The affected brain parenchyma is highlighted by the dashed outline. The collateral status is moderate (more than 25% but less than 50% filling of the leptomeningeal collaterals in the affected territory compared with the contralateral side) on the arterial (F) and peak venous (G) phase, and there is delayed washout in the late venous phase (H). (I) Sagittal image shows a posterior dominant middle cerebral artery MeVO (arrow). (J–L) Axial images show the (J) arterial, (K) peak venous, and (L) delayed venous phases of the baseline multiphase CTA examination. The affected brain parenchyma is highlighted by the dashed outline. The collateral status is poor, with almost no collateral filling.

TAE reduces pain in patients with chronic wrist pain
The finding suggests that the emerging interventional radiology procedure could be a new option for patients who have exhausted conservative management.
May 20, 2026
A 44-year-old woman with TFCC injury treated by transcatheter arterial embolization (TAE). a) Right brachial arteriography via common femoral artery access with a 5-Fr catheter demonstrates hyperstaining on the ulnar side of the wrist joint (white circle). b) An ulnar artery branch is superselected with a 1.9-Fr microcatheter, showing hypervascular staining corresponding to the pain site (white arrow). c) Delayed-phase angiography reveals early venous drainage (white arrow) adjacent to the hyperstaining, a finding often observed in TAE and considered an additional marker for embolization. d) Final angiography after injection of 0.5 mL quick-soluble gelatin sponge particles (QS-GSPs) demonstrates resolution of the hyperstaining (white circle). The VAS pain score improved from 7 at baseline to 1 at six months.

AI devices vary widely in lung cancer detection
Three devices helped detect more cancerous tumors, whereas the other four devices helped detect fewer tumors.
May 19, 2026
Cropped secondary capture examples. These are illustrative and not intended to imply superiority or inferiority of any device. (A) Posteroanterior radiograph in a 46-year-old female patient. The device correctly identified a right lower lobe nodule projected below the right hemidiaphragm and hilar lymphadenopathy. (B) Posteroanterior radiograph in an 86-year-old female patient with a classic Golden S sign highly suggestive of cancer. Three devices did not identify any findings. (C) The output from one device for the same radiograph as in B. The device placed a contour around the area of abnormality but mislabeled it as segmental collapse, and there are no other elements in the output to raise suspicion of cancer. (D) Posteroanterior radiograph in a 60-year-old male patient -- a case of confirmed lung cancer that was not deemed visible in retrospect. The device identified multiple false-positive abnormalities. (E) Posteroanterior radiograph in a 77-year-old female patient with two right lower lobe nodules. The device mislabeled the abnormality as infection -- a diagnostic term that could incorrectly influence clinical management. (F) Posteroanterior radiograph in a 77-year-old female patient with a right hilar tumor. Most of the lungs have been labeled by the device, with excessive overlap of the abnormality that pragmatically represents an incorrect result. All annotations shown were produced by the devices. LL = lung lesion, LO = lung opacity, PO = pleural other, TBC = tuberculosis.

ISMRM: Functional lung MRI detects asthma treatment responses
Biologic treatment of severe eosinophilic asthma is successful in only 80% of patients and predictive factors for treatment response are not yet available.
May 11, 2026
Representative PREFUL and F-19 MRI results at baseline and three months of a male responder (age: 47). First row: PREFUL ventilation images; Second row: Ventilation defect percentage (VDP) maps; Third row: Flow-volume loop (FVL) maps. VDP changed from 54% to 23% and the FVL score over the whole lung increased from 88% to 98%. Fourth and fifth rows: second breath-hold F-19 ventilation with corresponding VDP map; sixth and seventh rows: sixth breath-hold F-19 ventilation with corresponding VDP map. Second VDP decreased from 26% to 10% and 6th VDP from 16% to 3%.

New immuno-PET tracer shows promise in prostate cancer

A 74-year-old patient with metastatic prostate cancer with a positive left iliac wing lesion (SUVmax of 35.02) seen on (A) Zr-89 DFO-YS5 PET maximum projection image (MIP) and (B) PET/CT (red arrows). The lesion was graded 5 on PET but was not visible on CT (D) or (D) technitium-99 MDP bone scan.
