Educating Clinicians About LDCT May Increase Early Diagnosis
When general clinicians were educated about and given access to low-dose computed tomography, more lung cancers were diagnosed.
Dose Reductions Achievable in Pelvic CT with ASIR
Pelvic CT with filtered back projection and 50% ASIR reduces dose.
Dose Can be Reduced in Pelvic CT with ASIR
Filtered back projection and ASIR50 reduces dose in pelvic CT.
Lower Voltage CT Angiography Effective Even with Higher BMI
Study measures size-specific dose estimates and contrast-to-noise ratio in overweight patients.
Iterative Reconstruction Reduces Pediatric Chest CT Dose
Study examines ASIR effect on normal and overweight children who underwent chest CT.
LDCT Lung Cancer Screening: More Data for CMS
Study evaluates whether LDCT lung cancer screening is equally beneficial for younger and older patients.
Cone-Beam CT Best for Visualizing Hard-Contrast Objects
Cone-beam CT is preferential to multislice spiral CT for hard-contrast objects, study says.
Data Backs CT Lung Screening in More High-Risk Patients
NCCN Group 2 high-risk patients to benefit from CT lung screening, study says.
Model-Based Iterative Reconstruction Allows Lower Dose
CT images reconstructed with low dose model-based iterative reconstruction did not compromise image quality.
Many States Don’t Have Adequate LDCT Screening
States found to have a high percentage of people at risk for lung cancer do not have an adequate number of LDCT screening centers.
Varying CT Systems, Varying Risk Classification
New CT scanners’ variability affects cardiovascular risk classification.
Double Thoracic CT Used Appropriately Despite Doubts
Mainstream media may report CT overuse, but double thoracic CT is used appropriately, study says.
Which Phase Produces Interpretation Errors in CT Colonography?
Experienced and inexperienced radiologists had similar eye tracking, so errors may be occurring during other phases of the study.
Coronary CT Angiography Screening in At-risk Cancer Survivors
CCTA may be effective in screening CAD in adult survivors of Hodgkin’s lymphoma.
Automatic Tube Voltage Selection Reduced Radiation Dose
Automatic tube voltage selection automatically adjusts the tube current depending on patient size and attenuation.
LDCT for Lung Cancer Screening: The Effect of False-Positives
Patients who underwent low-dose CT for lung cancer screening and received false-positives benefited from counseling.
Substantial Dose Reduction Possible in CT of Pleural Effusions
Study identifies lowest possible radiation dose that still allows for detection of pleural effusions, thickening and calcification.
Positioning Essential for CT Dose and Image Noise
Study shows patients are positioned too low, negatively impacting radiation dose and image noise in chest CT.
Tomosynthesis Better at Identifiying Architectural Distortion
Tomosynthesis provides better visualization of architectural distortion than mammography.
It’s Not Why You Think: Choosing Contralateral Prophylactic Mastectomy
Study tackles why women with most treatable form of breast cancer pursue most aggressive prophylactic measures; MRI false-positives have no effect.
Mammography, MRI Combined Best for High-Risk Screening Program
Combining MRI and mammography in an organized breast screening program for high-risk women is effective.
LDCT for Lung Cancer: More Lung Cancers Earlier, But at What Cost?
The controversy of covering low-dose CT for lung cancer screening continues, as groups argue lives saved versus dollars spent.
Staff Training Reduced Pediatric CT Dose, Maintained Image Quality
Short but intensive training was effective in training radiology staff on dose reduction.
Breast Diffusion-Tensor Imaging Not Restricted by Menstrual Cycle
Timing of DTI is not restricted by the menstrual cycle, but is sensitive to menopause and milk in lactating women.
Preoperative MRI Reduced Reexcision Rates in Early Breast Cancer
Preoperative MRI in early breast cancer can reduce reexcision rates and, therefore, minimize patient anxiety.
Cost Savings in Breast Imaging
In cost comparison of screen-film mammography and digital mammography, digital is more cost-effective.
Institutions Rarely Used Reduced Dose Protocol in Renal Colic CT
Discrepancies in dose among institutions reveal underutilization of reduced-dose techniques.
Flaw in Radiation Reduction Efforts, One Size Doesn’t Fit All
Applying the same dose-reduction protocols to all patients may have adverse effects.
Ultrasound Better than MRI for Placenta Accreta Diagnosis
Ultrasound remains most sensitive imaging modality when diagnosing placenta accreta.
Chest Radiation as a Child Ups Risk for Breast Cancer Later in Life
Women treated with chest radiation as children have an increased risk for developing breast cancer later in life, a study says.
