What imaging modification is used to assess for gallbladder disease in acute cholecystitis?

Real-time ultrasound is the preferred imaging modification for assessing gallbladder disease, particularly in cases of acute cholecystitis. This technique allows for immediate visualization of the gallbladder and surrounding structures, enabling sonographers to evaluate key signs of acute cholecystitis, such as gallbladder wall thickening, the presence of gallstones, and pericholecystic fluid. The real-time nature of this imaging modality provides a dynamic view, which is essential for detecting the signs of inflammation and for assessing the patient's clinical condition.

Additionally, real-time ultrasound is non-invasive, does not involve radiation, and allows for an immediate assessment that can be crucial in emergency situations. Various sonographic signs can be directly evaluated during the examination, contributing to a timely diagnosis and management plan for the patient.
