Large pneumoperitoneum is rare because etiology of appendicitis involves obstruction of a very small lumen containing little air Focal increase in thickness of lateral abdominal wall Loss of properitoneal fat line on right side CT The imaging study of choice (>95% accurate) is CT, or US Signs o...
If the diagnosis remains inconclusive, a thoughtful conference with referring clinicians should help guide the radiologist's next imaging modality of choice. MRI is preferable to CT given radiation concerns. The MR findings of appendicitis include a dilated, thick walled blind-ending tubular structure ...
In adult patients, CT demonstrates superior sensitivity and specificity for appendicitis compared to ultrasound, with less variability, and is the imaging modality of choice in nonpregnant patients (strong evidence). In pediatric patients, CT has higher sensitivity than ultrasound, but similar ...
Bowel Imaging Acute appendicitis Acute appendicitis is the most common indication for urgent abdominal surgery and one of the most common causes of acute abdominal pain. It is more prevalent in older children and young adults. In most cases, this is the result of luminal obstruction usually by ...
of fever and abdominal complaints. The diagnosis may be suggested by history and examination (including presence of a right lower quadrant mass) and frequently is supported by imaging. The imaging of choice is of considerable debate: Ultrasound has traditionally been a useful tool given its ease ...
using appendicitis scoring systems to estimate the likelihood of appendicitis. Imaging (e.g., abdominal CT with IV contrast, abdominal ultrasonography) may be considered if the clinical diagnosis is uncertain. The current standard of management of acute uncomplicated appendicitis is appendectomy wit...
Although there has been much discussion about the merits of various modalities in the diagnosis, it is now clear that multidetector computed tomography (MDCT) is the imaging tool of choice. It is able to see the appendix easier than other methods, and ...
The “belly bloods” are back and they show a white-cell count of 11.1 and a CRP of 42 (the CRP is always 42) Given his young age and lean habitus it is felt that an ultrasound is the best imaging option for this man. The scan is normal aside from an obvious appendicitis. Notably...
Conclusions: Clinical assessment is the key to diagnose appendicitis. Nevertheless, in girls older than 10 years, selected use of imaging should be implemented to avoid unnecessary appendectomies. Imaging of choice in equivocal cases should be ultrasonography. 展开 ...
