Soft-tissue windows are good for determining some pathologic features, including orbital cellulitis/abscess, noninfectious inflammation, and tumors. May be useful in determining posterior scleral rupture when clinicalexamination is inconclusive, b...
The most common actions were calls to referring providers to modify or clarify an order (24.3%), followed by verification of proper premedication in patients with allergy to iodinated contrast (12.7%) and contacting the radiologist for protocolling (12.7%). Conclusions Implementation of a pre-CT ...
Drugs for sedation (n = 556, 0.3%), premedication for known or suspected contrast media allergy (n = 416, 0.2%), or perchlorates for hyperthyroidism (n = 62, 0.03%) were also utilized, but rarely. In patients undergoing CT for suspected CAD, beta-blockers and nitrates ...
In some instances, it might be preferable to begin with a low-dose CT scan of the body and then decide to add a diagnostic CT scan of a particular region, as the findings on the low-dose CT scan may influence the need for a contrast-enhanced or higher resolution regional view. High i...

(Partially reproduced from open access ref. no [58]) 373 function or allergy, appropriate measures are recommended such as intravenous hydration or pharmacological premedication, following guidelines from the European Society of Urogenital Radiology [17].

Allergy to i.v. contrast agents. If a PET/CT examination with i.v. contrast is required (see example above), it is important to be aware of any previous contrast reaction(s), which are classified as either idiosyncratic (anaphylactoid) or non-idiosyncratic. Premedication reduces the risk of...
It should explicitly include the request for performing the scan in the RT position. In most cases, the administration of intra-venous contrast will be requested, and, in these cases, kidney function (or glomerular filtration rate) and history of contrast allergy should be noted. Patient ...
Patients with a left ventricular ejection fraction <40%, chronic kidney disease (estimated glomerular filtration rate <60 mL/min/1.73 m2 within 30 days of the CT), intravenous contrast allergy, or underlying atrial fibrillation were excluded from this study. 2.2. Patient Preparation An oral and/...
