Hepatocellular carcinoma surveillance requires risk-adapted use of US, MRI, and emerging biomarker-based strategies to optimize early detection and clinical outcomes while maintaining cost-effectiveness and real-world feasibility.

Cross-sectional interventional radiology (CSIR) for the spleen has evolved over the past two decades. Contemporary data show that CT- and US-guided splenic procedures are safer than once assumed, allowing for biopsy and drainage when clinically appropriate. Prior to intervention, however, close imaging evaluation of splenic lesions is required in order to recognize definitively benign, “do not touch” lesions as well as suspicious features that might warrant biopsy. This manuscript will first focus on imaging workup and decision-making for splenic lesions, and then discuss modern CSIR techniques to maximize both safety and yield.

In a virtual imaging study, photon-counting CT improved the detection of small liver lesions (<1.5 cm) over conventional energy-integrating detector CT, particularly at lower dose levels.
