1. Computed tomography (CT) findings improved generalized estimating equation models predicting whether a patient would experience incomplete recovery or unfavorable outcome in mild traumatic brain injury. 2. Patients with contusion, subarachnoid hemorrhage, and/or subdural hemorrhage were more likely than those with other radiologic findings on computed tomography (CT) to have...

1. In this study comparing three prominent lung cancer screening strategies, all were found to be cost-effective, yielding incremental cost-effectiveness ratios of under $100,000/quality adjusted life-year gained, the commonly referenced U.S. willingness-to-pay threshold. 2. As the maximum age for screening eligibility increased, greater reductions in cancer mortality were realized but...

1. Computed tomography coronary angiography (CTCA) increased the certainty but did not significantly affect the frequency of the diagnosis of angina secondary to coronary artery disease compared to standard care alone. 2. CTCA was significantly associated with a change in planned investigations and treatments, including a greater reduction in...

1. Ultrasound- or computed tomography (CT)-guided ovarian mass biopsy yielded diagnostically sufficient samples with a sensitivity and specificity of 100% and 88%, respectively, for malignancy. 2. During the study period, ovarian biopsy procedures resulted in no complications, including no evidence of biopsy tract tumor seeding in patients with epithelial...

In this section, we highlight the key high-impact studies, updates, and analyses published in medicine during the past week. Ultrasonography versus Computed Tomography for Suspected Nephrolithiasis Thought to have increased sensitivity over ultrasound to detect kidney stones, CT has become the main diagnostic tool for the initial suspicion of nephrolithiasis. A...

1. Point-of-care (POC) ultrasound was equally effective as CT scan in identifying renal calculi at “high-risk” for complications at 30-days after assessment. 2. POC ultrasound reduced radiation exposure at the time of assessment in the emergency department as compared to CT scan. Evidence Rating Level: 1 (Excellent) Study Rundown:...

1. Contrast-enhanced dual-energy computed tomography (CT) may accurately differentiate benign adrenal adenomas from other potentially malignant lesions using fat-iodine material density analysis with a sensitivity and specificity of 96% and 100%, respectively. 2. Material-density analysis may allow non-invasive diagnostic evaluation of incidental adrenal masses based on the lipid-content as...

Image: PD  1. Individuals with colorectal cancer and liver metastases in this study undergoing PET-CT had a change in surgical intervention 8.0% of the time.  2. The disease-free and overall survival in individuals in this study with colorectal cancer and liver metastases was no different based on whether the individual underwent...
