F-18-FDG PET/CT in peritoneal tumors: a pictorial review
Pathologic involvement of the peritoneum can result from a wide range of conditions, including both non-neoplastic and neoplastic diseases. In the latter case, the peritoneum can be affected by primary tumors and, more commonly, secondary pathologic implants. In this heterogeneous spectrum of diseases, morphological imaging, especially computed tomography (CT), is the method of choice in detecting peritoneal implants as well as treatment response evaluation. F-18-fluorodeoxyglucose positron emission tomography/computed tomography (F-18-FDG PET/CT) is a reference technique in the oncological field and to date can be considered as a useful tool in the evaluation of peritoneal involvement. The purpose of this review is to describe the main F-18-FDG PET/CT features of peritoneal malignancies, to assess the potential use of F-18-FDG PET/CT for this disease and help in images evaluation
High-risk features in potentially resectable colon cancer: a prospective MDCT-pathology agreement study
Postoperative imaging in arthroscopic hip surgery
Arthroscopic surgery of the hip, compared to that of the knee or the shoulder, has only recently been developed in any significant way. Current indications for arthroscopic surgery of the hip include: diagnosis and treatment of lesions symptomatic of the acetabular labrum, femoroacetabular impingement (FAI), chondral lesions, joint infections, lesions of the teres ligament, impingement of the psoas tendon, pathology of the peritrochanteric space, external snapping hip (coxa saltans), and traumatic and atraumatic instability. Principal indications for imaging of the hip with arthroscopic techniques are represented by persistent groin pain which may be caused by inadequate recognition or treatment of bone alteration of FAI, fractures in the site of resectioned bones, intra-articular adhesion, development of cartilaginous lesions, iatrogenic chondral lesions, recurrent lesions of the fibrocartilaginous acetabular labrum and heterotopic ossification. Postoperative checkup examinations can be undertaken with conventional radiography. The appearance or persistence of groin pain may be investigated using MRI, arthro-MRI and even CT scans
Imaging of postoperative shoulder instability
Postoperative imaging in shoulder instability is still a challenge for radiologists due to various postsurgical anatomical findings that could be considered pathologic in treated shoulder. For this reason is very important a deep knowledge about surgical procedures, anatomical changes after surgery and the appropriate diagnostic imaging modalities to work up the symptomatic postoperative shoulder. Postoperative imaging options include use conventional radiography, magnetic resonance imaging (MRI), MRI arthrography, computed tomography (CT) and CT arthrography. The purpose of our review is to explain the different surgical procedures and to describe postoperative changes detected with radiological imaging
What can be seen after rotator cuff repair: a brief review of diagnostic imaging findings
Diagnostic imaging plays an important role in the postoperative evaluation of the rotator cuff, as pain and disability may occur or persist after treatment. Postoperative imaging is therefore of paramount importance for clinicians before planning additional treatments. Multimodality imaging of the postoperative shoulder includes radiography, magnetic resonance (MR) imaging, MR arthrography, computed tomography (CT), CT arthrography, and ultrasound. Correct interpretation of imaging findings of the postoperative shoulder necessitates that the radiologist be familiar with the various treatment strategies, their possible complications and sources of failure, knowledge of normal and abnormal postoperative findings, and awareness of the advantages and weaknesses of the different imaging techniques. Imaging findings, however, should always be correlated with the clinical presentation because postoperative imaging abnormalities do not necessarily correlate with symptoms. This manuscript is a review of some of the most common treatment strategies for rotator cuff pathology, with a focus on expected postoperative imaging findings and postoperative complications
