Images depict biopsy-confirmed prostate cancer in a 56-year-old man. (A) Pretreatment axial T2-weighted fast spin-echo MRI scan and (B) apparent diffusion coefficient map acquired with a 3T scanner show the tumor in the left transition zone (arrows). (C) Intraoperative 1.5-T MRI scan shows the contoured rectal wall (red line), prostate margin (blue outline), and region of interest (orange outline). (D) Intraoperative MRI scan shows a focused ultrasound beam path (blue) overlaid on the treatment plan. The rectangular boxes show each sonication spot. (E) Thermal map obtained during treatment shows heat deposition color-coded in red and overlaid on the sonication spot. (F) Axial gadobutrol-enhanced MRI scan obtained immediately after treatment shows the devascularized ablated volume (arrows). (G) Corresponding T2-weighted fast spin-echo 3T MRI scan obtained at 24 months after ablation shows fibrosis and volume loss in the left transition zone (arrows). Findings from a biopsy showed scar tissue, negative for malignancy at the treatment site.

PET lung scan times could be cut by half
By Will Morton
Dynamic PET scans acquired in half the time of normal scans appear clinically feasible for patients with lung lesions.
March 6, 2024
A 60-year-old male patient with clinical suspicion of lung cancer. PET/CT scan showed FDG-avid pulmonary nodules in the upper lobe of the left lung (red arrow), with a size of 2.2 × 1.3 cm, SUVmax of 12.2, Ki-65 min of 0.016 ml/g/min, and Ki-30 min of 0.014 ml/g/min. Surgical pathology confirmed a granulomatous lesion. In addition, PET/CT scan showed many FDG-avid lung nodules in the mediastinum. (A, static PET maximum intensity projection; B, static PET SUV image; C, static PET/CT fusion image; D, dynamic PET Ki-65 min image; E, dynamic PET Ki-30 min image). Image courtesy of EJNMMI Physics.
