Plain film radiography is often the first imaging modality employed in the assessment of patients with a rheumatological condition. More recently this has been superseded by cross-sectional imaging, in particular ultrasound and MRI, which have improved sensitivity in detection of early disease when compared with plain film imaging. However, there remains a role for conventional radiography in both the initial diagnosis and monitoring of disease progression. A standard approach to assessing radiographs in the context of arthropathy is usually employed by radiologists; by following this structured review a diagnosis or narrow differential may be reached on plain film imaging alone. Plain film radiograph findings of the most common rheumatological disorders are covered in detail in this chapter including osteoarthritis, the inflammatory arthritides, and crystal arthropathy. Findings in the connective tissue disorders are then covered, followed by less commonly encountered conditions such as SAPHO, neuropathic arthropathy, and haemochromotosis.

Transcatheter aortic valve replacement (TAVR) as well as thoracic and abdominal endovascular aortic repair (TEVAR and EVAR) rely on accurate pre- and postprocedural imaging. This review article discusses the application of imaging, including preprocedural assessment and measurements as well as postprocedural imaging of complications. Furthermore, the exciting perspective of computational fluid dynamics (CFD) based on cross-sectional imaging is presented. TAVR is a minimally invasive alternative for treatment of aortic valve stenosis in patients with high age and multiple comorbidities who cannot undergo traditional open surgical repair. Given the lack of direct visualization during the procedure, pre- and peri-procedural imaging forms an essential part of the intervention. Computed tomography angiography (CTA) is the imaging modality of choice for preprocedural planning. Routine postprocedural follow-up is performed by echocardiography to confirm treatment success and detect complications. EVAR and TEVAR are minimally invasive alternatives to open surgical repair of aortic pathologies. CTA constitutes the preferred imaging modality for both preoperative planning and postoperative follow-up including detection of endoleaks. Magnetic resonance imaging is an excellent alternative to CT for postoperative follow-up, and is especially beneficial for younger patients given the lack of radiation. Ultrasound is applied in screening and postoperative follow-up of abdominal aortic aneurysms, but cross-sectional imaging is required once abnormalities are detected. Contrast-enhanced ultrasound may be as sensitive as CTA in detecting endoleaks.

AbstractChronic neck infections in the pediatric population can have an indolent presentation that can mimic more serious conditions including neoplasia. Ultrasound remains a reliable primary modality for imaging of sialadenitis and infected congenital cystic neck lesions in children, whereas cross sectional imaging is needed if intervention is contemplated, to better evaluate multispatial involvement, lymph nodal morphology and distribution, and as the primary imaging modality to study more complex anatomy in case of ear infections.

Diagnostic imaging of the equine neck is undertaken for a wide variety of conditions. In many cases, radiography is the principal imaging modality, often complemented by ultrasound examination. Common conditions encountered include osteoarthritis, articular process joint osteochondral fragmentation, cervical vertebral malformation (‘wobbler’), fractures and numerous soft tissue lesions. The complex three-dimensional anatomy of the region limits interpretation of planar images and, in some cases, cross-sectional imaging (such as computed tomography) may be required. However, careful use of radiography and ultrasound can help clinicians to achieve a diagnosis in many cases, often from combining conventional and lesion-orientated projections with a thorough clinical examination.

Adnexal lesions are one of the most common cause of gynecological complains, including possibility of ectopic pregnancy in reproductive age group. Ultrasound is the first imaging modality used for evaluation of adnexal lesions. On ultrasound large non-adnexal lesions can be confused as adnexal lesions causing a diagnostic dilemma, rendering use of cross-sectional imaging mandatory. We present a case of middle-aged female who was diagnosed with a right adnexal lesion (possibly malignant) on ultrasound, but on further evaluation was found to be suffering from a benign non-adenexal etiology.

Background: The diagnosis of inflammatory bowel disease (IBD) is based on a combination of endoscopic, clinical and biochemical investigations as well as cross-sectional imaging. The applications of cross-sectional imaging in IBD are manifold. Ultrasonography has emerged as an important imaging modality in the diagnosis of Crohn's disease (CD) as well as for monitoring disease progression and in the therapeutic response to CD and ulcerative colitis (UC). Key Messages: Ultrasonography is non-invasive, radiation free, cheap, easy to use and well tolerated and accepted by patients. Bowel ultrasonography can be used for the primary diagnosis of CD as it has a similar sensitivity and specificity like that of MRI and CT, particularly in the case of CD. Ultrasonography can also be used to monitor treatment response to therapy and to detect disease recurrence of CD as well as UC. In CD, ultrasonography can also be used to detect complications such as strictures as well as extramural complications, including abscesses and fistulas. Contrast-enhanced ultrasonography is a useful tool that might be helpful to detect certain indications in CD, in particular the differentiation between abscesses and inflammation. Conclusion: A variety of advantages of bowel ultrasonography over other imaging modalities suggest the more frequent use of this method to manage IBD patients in daily practice. Bowel ultrasonography should be a standard tool in IBD centers.
