In a general population of emergency department patients with abdominal pain, using unenhanced CT to avoid risks of intravenous contrast medium administration is associated with a large diagnostic penalty. https://t.co/CVg04763yd

Study suggests there is little added value from follow-up pelvic CT after treatment of hepatocellular carcinoma
23 Feb, 2023 | 13:39h | UTCSummary: The study investigated the added value of pelvic coverage at follow-up liver CT in detecting pelvic metastasis or incidental tumors in patients treated for hepatocellular carcinoma (HCC). The study found that the incidence of isolated pelvic metastasis or incidental pelvic tumor was low in patients treated for HCC. The cumulative rates of isolated pelvic metastasis and incidental pelvic tumor were 1.4% and 0.5%, respectively, at 3 years. Only baseline T stage was associated with an increased risk of isolated pelvic metastasis. The study concludes that excluding the pelvic scan can reduce radiation dose and decrease the workload for radiologists. However, the study also had limitations, such as being retrospective and single-center. Therefore, more research is necessary to study the optimal scanning strategy for the pelvis and the effect of pelvic CT coverage on survival in patients with HCC.
