Postdeglutitive overflow aspiration is a frequent finding in patients with pharyngeal retention, and the risk of aspiration increases markedly with the amount of residue. Functional abnormalities other than pharyngeal weakness, such as impaired laryngeal closure, may contribute to aspiration.
• Potential surgical treatment requires accurate radiological assessment of colorectal liver metastases • Magnetic resonance imaging with gadoxetic acid is the preferred imaging investigation. • MRI is better than multidetector CT for detecting small liver metastases.
Background and Aims
Diagnosis and follow up of patients with inflammatory bowel disease [IBD] requires cross-sectional imaging modalities, such as intestinal ultrasound [IUS], magnetic resonance imaging [MRI], and computed tomography [CT]. The quality and homogeneity of medical reporting are crucial to ensure effective communication between specialists and to improve patient care. The current topical review addresses optimized reporting requirements for cross-sectional imaging in IBD.
Methods
An expert consensus panel consisting of gastroenterologists, radiologists, and surgeons convened by the ECCO in collaboration with ESGAR performed a systematic literature review covering the reporting aspects of MRI, CT, IUS, endoanal ultrasonography, and transperineal ultrasonography in IBD. Practice position statements were developed utilizing a Delphi methodology incorporating two consecutive rounds. Current practice positions were set when ≥80% of the participants agreed on a recommendation.
Results
Twenty-five practice positions were developed, establishing standard terminology for optimal reporting in cross-sectional imaging. Assessment of inflammation, complications, and imaging of perianal CD are outlined. The minimum requirements of a standardized report, including a list of essential reporting items, have been defined.
Conclusions
This topical review offers practice recommendations to optimize and homogenize reporting in cross-sectional imaging in IBD.
The purpose was to assess axial alignment of the lower limb using mechanical axis measurements on conventional and digital radiographs. Total-leg radiographs of 24 patients, 8 male and 16 female, with a mean age of 68.6+/-10.2 years, were performed in a standardized anterior-posterior projection and standing position using a conventional and digital phosphor storage film screen radiography system. Knee joint angulation was assessed by measuring the angle between a line drawn from the center of the femoral head to the middle of the femoral condyles and a line drawn from the middle of the tibial condyles to the midpoint of the malleolus. On conventional leg radiographs, line drawing and angle measurement were performed manually with a transparent goniometer. Angle measurement on digital leg radiographs was performed on a PACS workstation using computer-assisted measurement software (IMPAX, AGFA-GEVAERT, Belgium). Evaluation time for both measurements was recorded. We diagnosed 14 varus and 10 valgus angulations of the knee joint. The mean individual difference between axis deviation of conventional digital leg radiographs was 0.93+0.6 degrees (min 0 degrees, max 2 degrees), the mean difference in varus angulation was 1.13+/-0.45 degrees (min 0.3 degrees, max 2 degrees), and the mean difference in valgus angulation was 0.65+/-0.71 degrees (min 0 degrees, max 2 degrees). Angle measurements on conventional and digital radiographs did not show any statistically significant difference. Mean time exposure was 4.9 min/patient for manual and 1.08 min/patient for computer-assisted angle measurement (P<0.001). Computer-assisted angle measurement on digital total-leg radiographs represents a reliable method with no significant angle differences compared to conventional radiographic systems and offers a significantly lower evaluation time.
The aim of this study was to assess the role of videofluoroscopy in the detection of structural abnormalities of the pharynx and esophagus in patients with different symptoms of impaired deglutition. Dynamic radiographic recording of deglutition was performed in 3193 consecutive patients (1578 men, 1615 women; mean age 54 years) suffering from dysphagia, suspicion of aspiration, globus sensation, and non-cardiac chest pain. We assessed different structural lesions from the oral cavity to the esophagus and classified them into eight categories. Their frequency and association with the different clinical symptoms were evaluated. Videofluoroscopy revealed 1040 structural abnormalities in 833 patients (26%) including mass lesions from the oral cavity to hyoid/larynx ( n=66), pharyngeal diverticula ( n=181), pharyngeal masses ( n=78), other pharyngeal narrowings ( n=71), webs ( n=98), masses ( n=39), and other narrowings ( n=73) of the upper esophageal sphincter, esophageal diverticula ( n=80), esophageal webs, rings and strictures ( n=194), and intrinsic and extrinsic esophageal lesions ( n=160). There was a considerable variance of findings for different symptoms. In a large proportion of symptomatic patients videofluoroscopy detects morphological abnormalities along pharynx and esophagus often combined with functional disorders. This fact underlines the role of videofluoroscopy as a diagnostic test for function as well as morphology.
In a study with simulation of clinical conditions, performance of the LCD monitor and high-resolution CRT monitor for detection of support catheters on bedside chest radiographs was equivalent. With both displays, detection performance was equally reduced with bright ambient light.
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.
