Images of a 39-year-old who underwent screening mammography. Right craniocaudal (left) and mediolateral oblique (middle) views from preoperative mammography show suspicious grouped fine pleomorphic calcifications (arrows). After biopsy showed ductal carcinoma of situ (DCIS), patient underwent breast-conserving surgery, yielding final diagnosis of ductal carcinoma in situ (intermediate grade, hormone receptor positive). (Right) Screenshot of an output of a commercial AI tool applied to preoperative mammography. AI detected right breast lesion with score of 95% on both views (concentric colored circles). Present study’s reviewing radiologist deemed AI marking to correspond with site of DCIS.

Axial contrast-enhanced CT scan in a 28-year-old premenopausal woman shows an incidentally detected solid-appearing left ovarian lesion (solid arrow) anterior to the uterus (U), associated with trace ascites in the right adnexa and cul de sac (dashed arrows). At pathologic analysis, this was shown to be ovarian dysgerminoma. Two readers misdiagnosed this lesion, one as a leiomyoma and one as an ovarian fibroma.

SNMMI: New SPECT/CT radiotracer effectively images cardiac amyloidosis
By Kate Madden Yee
A new SPECT/CT radiotracer produces high quality and readily interpretable images of cardiac amyloidosis, researchers have found.

SNMMI: Image of the Year shows early brain nuclei activity
By Will Morton
Yale University researchers have won this year’s Image of the Year award at the SNMMI annual meeting for revealing brain nuclei activity with a dedicated brain PET scanner.
June 10, 2024
F-18 SynVesT-1 images at early (0-10) and late (90-120 minute) times postinjection. There is clear identification of high flow regions in the early images. The late images show the synaptic (SV2A) pattern which differs from the flow pattern, e.g., in the thalamus. B. 11C-PHNO binding potential (BPND) images shown in transverse, coronal, and sagittal orientations of PET alone and PET overlaid with MRI. Left: Region of substantia nigra (green arrow, max display: 4.0). Right: Thalamic region (max: 2.5) showing focal bilateral binding in a specific thalamic nucleus (blue arrow, likely anteroventral nucleus). C. Sagittal images of 11C-LSN3172176 M1 muscarinic cholinergic BPND (max display: 10). D. R1 images of the same tracer (max: 2). Cerebellum (blue arrow) shows no specific binding (C) and high tracer delivery (D). E. 18F-FE-PE2I dopamine transporter BPND images (zoomed, max display: 6) showing striatum and substantia nigra (green arrow). F. R1 images of the same tracer (max: 2) with inset showing zoomed region in E.

SNMMI: Can hearing aids benefit patients with cognitive impairment?
By Will Morton
Hearing aids may slow the metabolic decline that takes place in the brains of adults with mild cognitive impairment.
June 9, 2024
(A) Frontal cortical regions with below-normal metabolism (less than 5th percentile, displayed in color) at baseline, in subject with mild cognitive impairment and untreated hearing loss. (B) Frontal cortical regions with below-normal metabolism two years later. Brighter red colors correspond to more severely diminished metabolism. In contrast, the group of subjects using hearing aids did not undergo significant decline in any frontal cortical region over the same time period. Image courtesy of Natalie Quilala.
