Cancer death rates continue to decline in U.S.
The U.S. continues to see a decline in cancer mortality, according to the latest numbers published by the U.S. government on May 22 in Cancer. However, the figures also indicate a rising incidence of late-stage prostate cancer, possibly due to the decline in prostate-specific antigen screening.

Bone scan software predicts prostate cancer survival
Researchers using automated software to assess bone scintigraphy scans of patients with metastatic prostate cancer found that the algorithm helped them predict which patients were more likely to survive, compared with manual methods of interpreting the scans, according to a May 17 paper in JAMA Oncology.

Why don't patients show up for imaging exams?
Why don't patients show up for scheduled imaging exams? A study published May 10 in the Journal of the American College of Radiology that included nearly 3 million exams over 16 years found that no-shows are due to a mix of reasons.

EVT promising in patients with extracranial ICA occlusions
By Will Morton
Endovascular thrombectomy (EVT) and best medical treatment are both effective and safe options for patients with acute extracranial internal carotid artery occlusions.
January 21, 2025
Images in a 74-year-old male patient who presented at the hospital with acute symptoms of a right hemispheric ischemic stroke and a National Institutes of Health Stroke Scale (NIHSS) score of 24. (A) Nonenhanced CT image shows no signs of early infarction, whereas (B) CT perfusion image shows a large perfusion deficit in the territory of the middle cerebral artery and anterior cerebral artery caused by an extracranial occlusion in the right internal carotid artery. (C) Digital subtraction angiography shows the occlusion in the C1 segment. The extracranial occlusion was passed, reperfused, and subsequently stented (D, E). The final contrast injection did not reveal any intracranial occlusions within the territory of the internal carotid artery (F). At the 24-hour follow-up, there was no infarction on (G) the nonenhanced CT image, and the NIHSS score had decreased to 3 points. Image courtesy of RSNA.
CEUS resolves indeterminate CT, MRI liver observations
By Amerigo Allegretto
Contrast-enhanced ultrasound (CEUS) can resolve some high-risk indeterminate liver observations initially seen on CT or MRI.
January 21, 2025
Images depict a 49-year-old female participant with cryptogenic cirrhosis who presented with a 3.2-cm liver lesion. This biopsy-confirmed hepatocellular carcinoma (HCC) with an initial categorization of Liver Imaging Reporting and Data System (LI-RADS) category LR-4 (probably HCC) at CT was upgraded to LR-5 (definitely HCC) at contrast-enhanced ultrasound (CEUS). (A) Precontrast CT images in the liver show vague hypoattenuation in the medial left hepatic lobe (arrows). (B) Arterial phase images demonstrate no definite arterial phase hyperenhancement (arrows). (C) Washout and an enhancing capsule (arrows) on a late-phase image resulted in an LR-4 categorization. (D) B-mode ultrasound shows a round hypoechoic nodule (arrows). (E) An early-phase CEUS image shows clear arterial-phase hyperenhancement (arrows); (F) No washout at one minute (arrows), and (G) late, mild washout at four minutes (arrows) resulted in a CEUS LR-5 categorization.
