“…Peritoneal biopsy may have a relatively high diagnostic accuracy, but its utility is limited because of its invasiveness. 5 PET/CT can be used to detect abnormal uptake of the whole body. 14 , 15 Thus, PET/CT offers the advantage of locating both the primary lesions and peritoneal thickening.…”

“…The utility of peritoneal biopsy is limited because of its invasiveness, although it has high diagnostic accuracy. 5 Conventional imaging methods used to characterize peritoneal thickening, such as unenhanced computed tomography (CT) attenuation, enhanced CT, or magnetic resonance imaging, have some limitations in differentiating between the presence and absence of primary lesions, even if peritoneal thickening is identified. 6 , 7 …”

The aim of this study was to assess the value of 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) for the differentiation of peritoneal thickening of undetermined origin.This retrospective study included 103 patients (44 men and 59 women, age 59.2 ± 14.8 years) who had undergone 18F-FDG PET/CT for the evaluation of peritoneal thickening of undetermined origin. All 18F-FDG PET/CT images were visually interpreted, and the maximal standardized uptake values (SUVmax) were measured. We compared the role of 18F-FDGPET/CT with that of CT alone in detecting peritoneal thickening of undetermined origin. We also compared the differences between malignant and tuberculous peritoneal thickening in PET/CT parameters and clinical characteristics.The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy in detecting the primary cause of the peritoneal thickening were 76.2%, 78.9%, 94.1%, 42.9%, and 81.2%, respectively, for 18F-FDG PET/CT, and 58.3%, 84.2%, 94.2%, 31.4%, and 63.1%, respectively, for CT imaging. Malignant peritoneal thickening had significantly higher SUVmax than nontuberculous benign peritoneal thickening. However, tuberculous peritoneal thickening also had a high SUVmax. There were some factors that were significantly different between patients with tuberculous peritoneal thickening and those with malignant peritoneal thickening in our study; these included age, pattern of peritoneal thickening, and presence of ascites.18F-FDG PET/CT is useful for detecting the underlying cause of peritoneal thickening. Special attention should be paid to peritoneal tuberculosis, which has a high SUVmax and may mimic malignant peritoneal thickening. Multiple PET/CT parameters which were different in patients with tuberculous and malignant causes could be taken into consideration to make the differential diagnosis.

“…Although pathologic examinations may not be routinely performed for various diseases of the abdominal viscera, they are often necessary because an imaging diagnosis can be declared inconclusive. Ultrasound-guided percutaneous core needle biopsy (USPCB) is an accurate, safe, and widely accepted technique for the tissue diagnosis of various lesions of the abdominal viscera ( 1 ). Among various guidance tools such as US, computed tomography (CT), and magnetic resonance (MR) imaging, US has a number of advantages for guiding percutaneous biopsy for intra-abdominal lesions, including wide availability, portability, lack of ionizing radiation, relatively short procedure time, real-time visualization of the biopsy needle and target lesion during the procedure, ability to guide the procedure in almost any anatomic plane, fewer false-negative biopsies, and relatively lower cost ( 2 3 4 ).…”

Ultrasound-guided percutaneous core needle biopsy (USPCB) is used extensively in daily clinical practice for the pathologic confirmation of both focal and diffuse diseases of the abdominal viscera. As a guidance tool, US has a number of clear advantages over computerized tomography or magnetic resonance imaging: fewer false-negative biopsies, lack of ionizing radiation, portability, relatively short procedure time, real-time intra-procedural visualization of the biopsy needle, ability to guide the procedure in almost any anatomic plane, and relatively lower cost. Notably, USPCB is widely used to retrieve tissue specimens in cases of hepatic lesions. However, general radiologists, particularly beginners, find USPCB difficult to perform in abdominal organs other than the liver; indeed, a full understanding of the entire USPCB process and specific considerations for specific abdominal organs is necessary to safely obtain adequate specimens. In this review, we discuss some points and techniques that need to be borne in mind to increase the chances of successful USPCB. We believe that the tips and considerations presented in this review will help radiologists perform USPCB to successfully retrieve target tissue from different organs with minimal complications.
