Avoiding PACS installation mistakes

Does your facility see PACS as a necessary -- and expensive -- technology that you have to implement in order to stay competitive? Or is the network part of an overall strategic initiative, providing workflow benefits that will ripple throughout the healthcare enterprise? PACS consultant Gregg Cohen of Xtria Healthcare talks about common mistakes made during PACS implementation.

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.

Could AI scoring help with managing 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.

Clinicians, beware: CT diagnostic accuracy varies by adnexal lesion type

Images in a 55-year-old patient show hepatitis C-related cirrhosis and a transjugular intrahepatic portosystemic shunt (dashed arrow), with an undiagnosed tumor (dashed circle) at pretransplant imaging by both readers. Left: Noncontrast-enhanced axial CT image with a treated observation (dashed circles on the left, middle, and right images) and dense lipiodol staining (arrows) in the anterior right liver. Middle: Late arterial phase CT image with no appreciable enhancement. Right: Delayed phase image with no appreciable washout. The lesion was deemed at explant pathology to have 20% necrosis.
