Rare finding detected on PSMA-PET: A nonprostatic lung tumor
A group in Australia has described a rare finding during a prostate cancer restaging PET/CT scan – a pulmonary tumor embolism.
September 25, 2023
Hybrid contrast-enhanced CT (with iodinated contrast bolus timed to maximize pulmonary arterial visualization) and F-18 DCFPyL PSMA-PET images. Contrast CT images (A, B) show an eccentric filling defect in the superior lingula segmental artery of the left lung upper lobe (red arrow). This is concordant with moderately intense PSMA radiotracer expression (black arrows on axial PET-only images, C, and on whole-body maximum intensity projection image, E). Fused PET and contrast-enhanced CT axial image (D) also confirm the lesion (red arrow). No other site of PSMA expressing metastasis is evident on whole-body imaging (E).

PET/MRI predicts survival in endometrial cancer patients
PET/MRI scans show the progression of endometrial cancer in patients and may help predict survival outcomes.
September 19, 2023
Images of a 69-year-old woman with endometrial cancer, grade 1 endometrioid adenocarcinoma, T1aN0M0, stage IA. Sagittal (a) and axial (b) T2-weighted MRI show an endometrial tumor (arrow), without deep myometrial invasion. The tumor (arrow) is hyperintense on diffusion-weighted imaging (c) and hypointense on the ADC map (d). The ADCmin of the tumor was 0.45 × 10−3 mm2/s, and the ADCmean was 0.58 × 10−3 mm2/s. PET (e) and PET/MRI fusion images (f) show intense FDG uptake of the tumor (arrow). The SUVmax of the tumor was 12.5, MTV was 3.9 mL, and TLG was 29 g.

Does the PI-RADS update change prostate cancer treatment staging?
PI-RADS upgrade and downgrade rates from targeted MRI biopsy to radical prostatectomy haven't changed between PI-RADS version 2.0 and 2.1.
September 22, 2023
62-year-old patient with serum PSA level of 4.11 ng/mL. Prostate MRI shows lesion in left midanterior transition zone. Lesion (arrow) shows hypointensity on T2-weighted image (A), hyperintensity on high b-value DWI (B), hypointensity on ADC map (C), and focal early enhancement on dynamic contrast-enhanced image (D). Lesion was assessed as category 4 using PI-RADS version 2.1 MRI-targeted biopsy of lesion revealed prostate adenocarcinoma with ISUP grade group 2. At subsequent radical prostatectomy performed 6 months after biopsy, ISUP grade group was upgraded to 3. ISUP, International Society of Urogenital Pathology. Image courtesy of AJR.
