The technology of CT has made significant strides in the past few years, first with the development of spiral/helical scanning and more recently with multislice/multidetector CT scanning capability. These technological developments have opened the doors to new and improved applications for CT scanning. An understanding of these advances will provide career growth opportunities for technologists working in CT. This seminar will provide an improved understanding of multislice/multidetector CT as well as scan protocols, quality control procedures, and ACR accreditation procedures and requirements. Advancements in clinical applications of this technology will also be reviewed.

![A normal mammogram confirmed by three-year radiologic follow-up illustrates reader-marked regions of interest (ROIs) during (A) unaided (round 1) and (B) artificial intelligence (AI)–assisted (round 2) reading. Each colored dot represents an ROI for recall by a human reader. Readers could mark more than one ROI per case, represented by multiple dots of the same color. During AI-assisted reading, the AI system displayed three visible prompts: two with suspicion of malignancy scores of 35% (left mediolateral oblique [L MLO] and craniocaudal [L CC]) and one with a suspicion of malignancy score of 10% (right craniocaudal [R CC]), shown as polygonal overlays. Without AI, six of 10 readers (60%) marked a false-positive ROI. With AI assistance, this fell to two of 10 (20%). R MLO = right mediolateral oblique.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/07/2026-07-14-radiology-mammogram-ai-auto-bias.H0bYO8QlWs.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
