Adenomyosis is a benign tumor that occurs on the wall of the gallbladder, and can be examined by CT or MRI, there is no question of which one is more accurate, and both methods have their own advantages and disadvantages. 1. CT examination: for the investigation of adenomyosis of the gallbladder, it is generally recommended to do enhanced CT, through which the severity of adenomyosis of the gallbladder can be clarified, and the thickness of the wall of the gallbladder can also be determined. Through this examination, it can also identify with gallbladder distortion, cholecystitis and gallbladder cancer. 2. Magnetic resonance examination: Magnetic resonance examination of adenomyosis of gallbladder can diagnose whether there is hyperplasia of gallbladder muscular layer and preliminarily exclude malignant lesions, but similar to enhanced CT, it can not accurately assess the nature of the tumor. The above tests should be performed under the guidance of a medical professional, and if accurate differential analysis is desired, color Doppler flow imaging can also be used for diagnosis. Pathologic biopsy should also be performed if there is concern about the risk of cancer.
