Abstract
MDCT with advanced imaging processing is a powerful
diagnostic non invasive tool that can clearly illustrate the hepatic
arterial anatomy and its anatomical variants.
CTA by different imaging processing parameters requires proper
technique, including adequate scan protocol, optimization of
contrast delivery, and selection of appropriate phase of imaging
acquisition.
MDCT with advanced imaging processing and CTA allow early
detection of hepatic tumors, their number, sizes, segmental
location, and hypervascularity. In addition, it can easily
differentiate between benign and malignant varieties by
visualization of feeding arteries, draining veins, central scars and
septations.
Also, volume display is an important prerequisite before
operative tumoral resection as it determines the respectability of
the lesions; as well it can select patients with hepatic metastases
who would benefit from hepatic arterial chemotherapy pump
implantation.
Uncommon hypervascular liver lesions that simulate tumors
could be clearly delineated by MDCT with advanced imaging
processing; This will reduce the false positive diagnosis of
hypervascular hepatic tumors.
