Image perception: Are radiologists akin to MLB batters?
A radiologist’s perception when viewing a complex MRI may be akin to a Major League Baseball (MLB) batter reading the stitches on a fastball, according to researchers exploring how diagnostic interpretations are made.

FAPI-PET/CT outperforms FDG-PET/CT in women with invasive breast cancer
PET/CT imaging using gallium-68 FAPI radiotracer over F-18 FDG appears promising in women with invasive lobular carcinoma.

Maximum-intensity projection F-18 FDG-PET (left) and Ga-68 FAPI-PET (right) images of synchronous ILC. (A) A 42-year-old patient with multicentric primary lesions (encircled), regional (solid arrows), and distant inferior jugular lymph node (dashed arrows) seen on F-18 FDG-PET and subsequently confirmed on Ga-68 FAPI-PET, which also revealed additional malignant foci aligned with MRI. Some lesions exhibited high activity retention on Ga-68 FAPI-PET. (B) A 53-year-old patient showing no significant uptake on F-18 FDG-PET but synchronous bilateral lesions (arrows) on Ga-68 FAPI-PET, which also identified pathologic lymph nodes (encircled), resulting in upstaging.

AI flags rare humeral bone tumors on chest x-rays
An AI algorithm can help identify rare tumors on upper arm bones in patients undergoing chest x-rays – findings not typically identified in daily reading practice.

The tumor localization/visualization results obtained by the proposed AI algorithm. Original chest x-ray images with a lesion (red circle = radiologists’ annotation of the lesion location) and AI's lesion localization result. These examples demonstrate that the proposed technique can successfully detect humeral tumors. Image and caption courtesy of Radiology: Artificial Intelligence.

Image of patient (upper-left) in which, according to the radiologist's report, there is only consolidation, but the algorithm detects an abnormal rib (upper-right), consolidation (lower-left), and two nodules (lower-right). It is worth noting the confusion of a consolidation with mammary tissue and of two nodules with the two mammary areolae. Image courtesy of Scientific Reports.

PET lung scan times could be cut by half
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.

Is ‘theragnomics’ the future in molecular imaging?
Combining theranostics and radiomics – a new concept termed “theragnomics” – could be the key to realizing the full potential of molecular imaging of cancer patients.

Question 4 from the Japan Diagnostic Radiology Board Examination 2024, representing a clinical scenario of a man in his 30s presented with transient dysphasia. The question asks to identify the most probable diagnosis from the following options: (a) glioblastoma, (b) hemangioblastoma, (c) metastatic brain tumor, (d) oligodendroglioma, and (e) primary central nervous system lymphoma (PCNSL). The correct answer is (d) oligodendroglioma. The figure also includes a summary of responses from four large language models, along with their legitimacy scores rated by diagnostic radiologists.
