Ignoring breast CAD detections cuts sensitivity
Computer-aided detection (CAD) is effective at finding breast cancers -- including lesions that would have otherwise been missed by experienced radiologists. Unfortunately, CAD's overall benefit is diluted by the downside of radiologists ignoring true-positive CAD marks.

CT reveals acute PE risk in patients with severe swine flu
Minimizing the mortality associated with the H1N1 flu virus, also known as swine flu, will require creative use of various tools to assess the disease and its severity. For that task, chest CT is emerging as a useful modality, both to confirm H1N1 diagnosis and, as shown in a new study, to assess lung damage in the most seriously ill patients.

CT can aid early swine flu diagnosis
As the world awaits a vaccine to stave off H1N1 and hopes for the best, radiologists are finding that thoracic CT can aid early identification of the influenza known commonly, if inaccurately, as swine flu. A new paper in the American Journal of Roentgenology shows how CT detected a case that had shown a false-negative result on an H1N1 rapid antigen test.

ACRIN: Virtual colonoscopy sensitive for flat polyps
Refuting the idea that virtual colonoscopy is as blind as love to flat polyps, a new study of data from the National CT Colonography Trial (ACRIN 6664) found that VC prospectively detected more than two-thirds of flat adenomas, and nearly 90% were visible in retrospect.

ACRIN: Mammo bows to MRI for presurgical planning
ARLINGTON, VA - Compared to mammography, contrast-enhanced MRI is more accurate for predicting both the diameter and volume of residual tumors in women who received chemotherapy for locally advanced breast cancer, according to research presented at the American College of Radiology Imaging Network (ACRIN) fall meeting.

Symptomatic patients with zero CT calcium scores still have cardiac events
Evidence spanning decades shows that people with coronary artery calcium (CAC) scores of zero have a good chance of avoiding cardiac events. But the assurance applies only to asymptomatic patients. Newly emerging research finds that a zero CAC score combined with symptoms of coronary artery disease can mean trouble down the road.

VC excels at diverticulosis staging
Although virtual colonoscopy practice has always focused on adenoma detection and colon cancer prevention, the exam is proving to be formidable in the staging of diverticular disease, a scourge of fast-food Western nations that affects most of their citizens by age 60.

TCT: Plaque morphology imaging improves PCI outcomes
SAN FRANCISCO - A growing body of evidence is showing that plaque morphology is even more important than degree of stenosis in predicting outcomes of percutaneous coronary intervention (PCI). But precisely which imaging methods are the most effective, and ways in which they can improve interventional outcomes, still needs clarification.

CT, MRI look at different etiologies for myocardial fat
New studies appearing in Radiology online examine two different etiologies associated with myocardial fat deposits. Their presence on imaging studies, both in CT and MRI, can help radiologists evaluate the extent of disease and potential risks.

PET/CT improves diagnostic biopsy rates in lung cancer patients
By Will Morton
PET/CT imaging can serve as a metabolic guide to increase the accuracy of needle biopsies in patients with suspicious lung nodules.

Patient with extensive lung and pleural disease. (2a) The PET/CT was available prior to the biopsy showing heterogeneous F-18 FDG radiotracer uptake and delineating the most accessible area of increased metabolic activity. (2b) The biopsy was targeted to the area of increased activity area and was positive for malignant diagnosis. Image courtesy of the European Journal of Radiology.

PET/CT scans show value in patients with rare type of pancreatitis
By Will Morton
F-18 FDG-PET/CT scans may help predict relapses in patients with autoimmune pancreatitis.
January 19, 2024
F-18 FDG-PET/CT images of patients. (A) Image of a 61-year-old male patient with type 1 autoimmune pancreatitis (AIP) demonstrating diffuse enlargement of the pancreas (arrows). The serum IgG4 level was 2,260.0 mg/dL, and the TLG2.5 was 413.8 g/ml×cm3. According to the nomogram, his relapse probability is more than 95%. The patient discontinued steroid use during the maintenance phase, and 7 months later, he relapsed, with imaging showing diffuse re-enlargement of the pancreas. (B) Image of a 60-year-old male patient with type 1 AIP, showing focal enlargement in the head of the pancreas (arrows). The serum IgG4 level was 980 mg/dL, and the TLG2.5 was 92.7.0 g/ml×cm3. According to the nomogram, the patient’s relapse probability is less than 50%. After symptom relief, the patient did not receive maintenance treatment, and has been followed up for 4 years without relapse. Image courtesy of BMC Gastroenterology.
