DECT differentiates lung lesions with material decomposition
Tuesday, December 1 | 11:10 a.m.-11:20 a.m. | SSG03-05 | Room S404CDIn this study, researchers from Boston investigated the characteristics of lung abnormalities seen on material decomposition images from dual-energy CT (DECT).

Review course: Today's stroke triage tools
Tuesday, December 1 | 8:30 a.m.-8:55 a.m. | RC305-01 | Room N230How are today's neuroradiologists handling stroke triage? Perfusion CT and perfusion-weighted MRI can assess for ischemic stroke, hemorrhage, vasospasm, brain tumors, seizures, and traumatic brain injury. But not everything is appropriate for every case, according to Dr. Max Wintermark from Stanford University.

Tube current modulation vs. size-specific dose estimates
Monday, November 30 | 10:50 a.m.-11:00 a.m. | SSC10-03 | Room S504CDSize-specific dose estimates (SSDEs) are credited with bringing new levels of accuracy to radiation dose estimates by allowing dose to be tailored to patient size in a straightforward way. But how well SSDE works with automated tube current modulation, another mainstay of CT imaging, is still up for debate.

DECT measures treatment response in pancreatic cancer
Sunday, November 29 | 11:45 a.m.-11:55 a.m. | SSA06-07 | Room E353ATumor volume often falls significantly after chemotherapy, but the drop in iodine uptake may be more significant for prognosis. A group from Johns Hopkins University measured treatment response using iodine uptake with dual-energy CT (DECT) before and after treatment of pancreatic cancer.

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.
