R-SCAN offers resources that cover the spectrum of Choosing Wisely topics. Access a compendium of these resources here.
Avoid ordering CT of the abdomen emergency department (ED) patients (age <50) with known histories of kidney stones, or urolithiasis, presenting with symptoms consistent with acute uncomplicated renal colic.
Don’t routinely order coronary computed tomography angiography for screening asymptomatic individuals.
Avoid admission or preoperative chest x-rays for ambulatory patients with unremarkable history and physical exam.
Do not perform chest CT angiography to evaluate for possible pulmonary embolism in patients with a low clinical probability and negative results of a highly sensitive D-dimer assay.
Do not recommend follow-up imaging for clinically inconsequential adnexal cysts.
Don’t perform PET, CT, and radionuclide bone scans in the staging of early prostate cancer at low risk for metastasis.
Don’t perform advanced imaging (eg, MRI) of the spine within the first 6 weeks in patients with nonspecific acute low back pain in the absence of red flags.
Don’t order sinus CT or indiscriminately prescribe antibiotics for uncomplicated acute rhinosinusitis.
Don’t do imaging for uncomplicated headache.
CT scans are not necessary in the immediate evaluation of minor head injuries; clinical observation / Pediatric Emergency Care Applied Research Network criteria should be used to determine whether imaging is indicated.
Avoid computer tomography (CT) scans of the head in emergency department patients with minor head injury who are at low risk based on validated decision rules.
Neuroimaging (CT, MRI) is not necessary in a child with simple febrile seizure.
Don't recommend ultrasound for incidental thyroid nodule in low-risk patients unless the nodule meets age-based size criteria or has suspicious features.
