Although MRI has limitations such as suboptimal depiction of small implants and adhesions, this technique is very useful to guide laparoscopy. Moreover, the optimal concordance (95%) between our proposed MRI staging and the AFS laparoscopic classification demonstrated a new advantage of MRI in preoperative staging of endometriosis.
Angiosarcoma is a rare soft tissue sarcoma that usually occurs in deep soft tissues, breast, spleen, liver, and bone. Primary thoracic parietal localization of angiosarcoma is rare and prognosis is poor. In this report, we present the CT and PET features of a patient with pseudomesotheliomatous angiosarcoma of the chest wall and pleura, which, to the best of our knowledge, have not previously been described.
Spectral waveform and RI are associated with the length and caliber of the type of hepatic artery anastomosis used. End-to-end anastomoses are short and have a uniform small caliber; aortohepatic bypasses are longer and have a progressively by smaller caliber. We must be cognizant of the method of anastomosis used when examining patients for complications after liver transplantation because the method used affects the resulting spectral waveform and RI.
Pancreatic imaging is an essential tool in the early diagnosis and staging of pancreatic disease. This review analyzes the most recent advances in pancreatic imaging. The specific modalities discussed include helical computed tomography (HCT) and multislice CT (MSCT), CT angiography, magnetic resonance imaging (MRI), magnetic resonance cholangiopancreatography (MRCP), and positron emission tomography (PET). At present, MSCT is generally viewed as the most efficient modality for initial detection and staging of pancreatic carcinoma, with an accuracy rate of about 95% to 97% for initial detection and virtually 100% for staging. CT is also the initial imaging modality used in evaluation of acute pancreatitis. However, recently, MRI has been viewed increasingly as a more precise diagnostic tool in this subgroup of patients. MRCP has been accepted as the primary imaging technique in the diagnosis of chronic pancreatitis. PET imaging, on the other hand, has an increasing role in the staging of pancreatic carcinoma, for which it may be the modality of choice in detection of extrapancreatic metastasis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
