Bowel ultrasonography in acute abdomen: beyond acute appendicitis.

2021

Acute abdomen is a common reason for consultation in the emergency department. A broad spectrum of entities, including diverse diseases of the gastrointestinal tract, can cause acute abdomen. Although computed tomography is the technique most widely used to evaluate acute abdomen in the emergency department, abdominal ultrasound is often performed first and allows bowel disease to be suspected. This article describes the ultrasound features of diverse bowel diseases that can cause acute abdomen, such as acute diverticulitis, bowel obstruction, gastrointestinal perforation, bowel ischemia, intraabdominal fat necrosis, and miscellaneous processes such as endometriosis, foreign bodies, or vasc…

MR Imaging of Perianal Crohn Disease: The Role of Contrast-enhanced Sequences

2017

The MR imaging protocol described by the authors includes contrast-enhanced T1-weighted imaging with fat saturation in all patients except those with poor renal function. Horsthuis et al demonstrated in 2009 the usefulness of contrast-enhanced MR imaging for determining disease activity. Contrast agent administration is also required in case of suspicion of neoplastic tissue complicating fistulas. The joint European Crohn’s and Colitis Organisation–European Society of Gastointestinal and Abdominal Radiology guidelines report that T2-weighted images and contrast-enhanced T1-weighted images are included in the MR imaging protocol for the evaluation of perianal CD. However, as we have demonstr…

[I062] The roles of radiographers in medical imaging and radiotherapy in Europe

2018

Very fast development of technologies in medical imaging and therapy has changed the role of radiographer in Europe. Over the past ten years education and necessary skills and competencies for radiographers has become more similar in most EU countries due to input of EFRS Educational Wing, but there are still rather significant differences in the roles of radiographers between countries. Role expansion is often initiated by external and internal factors that lead to advanced practice for radiographers. However, there is also a limiting factor that functions as a barrier for development of radiographer’s role and mainly that is connected to resistance when radiologists/medical physicists obj…

Intraosseous gas distribution as a marker of postmortem interval

2020

Abstract The postmortem interval is probably the most important puzzle piece in clarifying the circumstances in case of death occurred in unknown conditions. Over the years, radio-imaging modalities have proved their worth in forensic field, providing additional and significant improvements and findings. CT-scan is characterized by wide availability, fast scan times and sustainable healthcare costs. Detection of gas, hemorrhage and bone fractures are points of strength of CT-scan. A reliable evaluation of the post-mortem interval is interesting in the victims of a mass disaster, also following a natural disaster, for the individuation of responsibility in the efficiency of the help and assi…

An atypical clinical presentation of acute appendicitis in a young man with midgut malrotation

2007

Abstract Midgut malrotation occurs as a result of failure in normal intestinal rotation and fixation during early pregnancy. Pathological conditions reported in the literature involving midgut malrotation predominantly relate to infants and children. In adults malrotation is often revealed as an incidental finding on computed tomography (CT), or the associated altered anatomy can be the cause of atypical clinical symptoms of relatively common intestinal disorders. An unusual presentation of acute appendicitis, with fever and recurrent pain in left iliac fossa is reported. Underlying intestinal malrotation delayed the correct clinical diagnosis of acute appendicitis. It was not until a CT sc…

Möglichkeiten und Grenzen der Spiral-CT bei der Untersuchung von Nierenbeckenkarzinomen

1994

PURPOSE To assess the value of spiral CT in comparison to conventional CT in the staging of renal pelvic carcinoma. PATIENTS AND METHODS 35 patients with renal pelvic carcinoma underwent preoperative CT; conventional technique (n = 21) and spiral CT (n = 14) with the reconstruction of thin sections were compared. RESULTS Non-invasive or minimal invasive tumours (TA, T1, T2) could not be differentiated with either technique. Small, flat tumours (TA) or multicentric tumours may be missed, even if spiral scanning is applied. The separation of local tumour growth from infiltration is significantly improved by spiral CT (12 of 12 patients instead of 18 out of 21 patients with the conventional te…
