1. In a retrospective review of 125 patients with primary renal cell neoplasm that underwent computed tomography (CT), simple renal cysts were found to have a mean attenuation value up to 30 Hounsfield Units (HU) on contrast-enhanced CT, while the lowest attenuation value of homogenous renal cell neoplasms was...
  1. In a prospective trial of 168 patients with suspected acute appendicitis (AA), patients that underwent external compression (EC) computed tomography (CT) demonstrated higher specificity for the diagnosis of acute appendicitis compared to standard CT scan. Evidence Rating Level: 2 (Good)            Study Rundown: In patients with suspected AA, imaging with ultrasound...
1. In a retrospective cohort study of 12 patients with psoriasis, 8F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) demonstrated significantly increased arterial inflammation and subcutaneous adipose tissue inflammation compared to healthy controls. Evidence Rating Level: 3 (Average) Study Rundown: Psoriasis is a chronic, inflammatory skin disorder associated with an increased...
1. In a retrospective review of 72 patients with renal stones that underwent unenhanced computed tomography (CT) followed by contrast-enhance CT in the portal venous phase, the overall sensitivity of contrast-enhanced CT for stones greater than 2mm in size was 99%. Evidence Rating Level: 3 (Average) Study Rundown: Renal stone disease...
1. In a case series of 23 infants with Zika virus infection, computed tomography (CT) of the head demonstrated a high prevalence of punctate intracranial calcifications, primarily within the frontal and parietal lobes with associated severe lateral ventriculomegaly. 2. Other common, non-specific brain findings include global hypogyration, cerebellar hypoplasia, and...
1. In a retrospective review of over 100 patients who experienced low-velocity trauma with computed tomography (CT)-proven head or cervical spine injury but without evidence of other bodily injuries, completion of a CT scan of the chest, abdomen, and pelvis (CT CAP) demonstrated no additional injuries. 2. Even in the...
1. In a prospective survey of over 240 emergency physicians, the use of computed tomography (CT) scans in emergency department significantly altered the leading diagnoses between the pre-test and post-test state while increasing diagnostic certainty across a variety of patient presentations. 2. Changes in leading diagnoses occurred most frequently with...
1. In patients with suspected acute appendicitis, baseline computed tomography (CT) studies identified predictors of surgical management, same-day discharge and repeat imaging or representation within 30 days, thereby secondarily predicting the costs of associated hospitalization and resource use. 2. Findings on CT showed that small appendiceal diameter, absence of periappendiceal...
1. In a retrospective review of over 190 patients with primary lung cancers, patients with lower grade emphysema and airway-predominant disease as determined by pulmonary computed tomography had a significantly higher frequency of central lung cancers as compared to patients with severe emphysema. Evidence Rating Level: 3 (Average)        Study Rundown: Chronic...
1. Computed tomography derived imaging characteristics were correlated with disease specific gene expression to create a radiogenomic based surrogate of molecular assays (SOMA) in patients with clear-cell renal cell carcinoma (CCRCC) which was predictive of disease-specific and stage-independent survival in a validated cohort. 2. Radiogenomic based SOMAs can theoretically be...
