A study found that MR imaging identified 86% of residual disease, outperforming mammography in detecting disease near the lumpectomy site. The imaging modality was also most accurate in identifying disease in different quadrants than the original tumor site.
A study of 716 consecutive emergency head CT examinations found general radiologists and neuroradiologists were in agreement on 95% of studies. The study suggests that general radiologists can accurately interpret emergency CT scans with high accuracy rates, similar to neuroradiologists.
A new study suggests that CT readings at oncology centers differ from those at general hospitals, affecting relative value unit assessments (RVUs). The average length of CT reports and character counts were significantly higher at oncology centers, with prior scans being directly compared more often.
The study found that voice recognition technology has reduced report time turnaround from 133 hours to 66 hours, with preliminary reports available within 14 hours. However, technical issues such as freezing and interfacing problems with RIS systems have led to decreased productivity and satisfaction among radiologists.
Researchers found that women who underwent pelvic arterial embolization experienced no significant long-term side effects, including fertility preservation. The procedure also showed a shorter recovery period compared to hysterectomy.
A new radiology procedure has been shown to alleviate pain caused by uterine fibroids, with all nine patients experiencing significant symptomatic improvement. The procedure involves blocking blood flow to the affected area using special particles or spheres, resulting in normal menstrual periods and no hormonal changes.
A new imaging technique using hyperpolarized helium MRI offers a noninvasive method to study the airways of people with asthma. The technique provides information on ventilation and depicts structure and function of the airways, which can help correlate symptoms with treatment.
A study found that recent radiologists interpreted screening mammograms more accurately than those with less training, while facilities with higher diagnostic volume showed improved accuracy. The researchers suggest additional studies to clarify the complex relationship between radiologist experience and mammogram interpretation.
Researchers will study ultra high field magnetic resonance imaging (MRI) to develop clearer, more precise images of the body's interior. The goal is to improve diagnosis and treatment for patients.
A new study demonstrates that learning and speech therapy can alter the way compensatory pathways in the brain work after a stroke. The research supports the hypothesis that brain pathways in the right hemisphere are directly involved in the recovery of language skills.
A study of community radiologists' mammogram interpretations found wide variation in how often masses, calcifications, and suspicious lesions are detected. False-positive readings increased with patient demographics, training level, and time since graduating from medical school.
Researchers at Johns Hopkins Medicine found that percutaneous vertebroplasty can be performed safely without venography in most cases. The study showed that 205 consecutive procedures without venography resulted in no major complications or cement leakage, with over 80% of patients experiencing major pain relief.
A study found that high-volume mammography readers in the US detected fewer cancers than their British counterparts, despite meeting lower annual standards. The research suggests re-engineering US screening programs to improve efficiency and quality without increasing interventions.
A biomedical engineer has developed a 'sonic flashlight' that combines ultrasound images with the patient's natural appearance, enabling doctors to guide procedures without looking away. This technology could improve hand-eye coordination and reduce learning curves for radiologists.
A study published by Dr. Dean Shibata found that people's brains use both rational and emotional parts when making personal decisions. When asked to choose between options, the ventromedial frontal lobe showed increased activity in the brain.
A study of 13,958 Canadian women found that the median time from screening to first assessment was 2.6 weeks and to diagnosis was 3.7 weeks. Women with breast cancer waited shorter times than those with benign findings. However, even with expedited investigations, 10% of women with breast cancer still waited over 12 weeks for a diagnosis.
A new study by Cincinnati Children's Hospital Medical Center reveals that some children receive five times more radiation than necessary during CT scans. Researchers found that adjusting technical factors like tube current and pitch can significantly reduce exposure without sacrificing image quality.
A study published in Radiology found that women who receive further testing on the same day as an abnormal screening mammogram experience significantly less stress than those who have to wait. The researchers also found that offering immediate diagnostic imaging can reduce the stress of a false positive mammogram, but would increase ov...
A study published by Indiana University School of Medicine found that men and women process language in different ways, with men using only the left side of their brain. The research may have implications for understanding how men and women recover from stroke and brain tumors, as well as improving imaging technologies.
A team of researchers found that radiologists prefer different images for evaluating various breast tissue abnormalities, requiring new computer programs for optimal results. The technology holds great promise in finding breast cancer earlier, but optimizing images for different tasks is crucial.
A new study finds that digital mammography provides better information for diagnoses, allowing radiologists to use multiple views of images. The technology has the potential to lead to earlier tumor detection and treatment, reducing breast cancer mortality rates.
A recent study at Wake Forest University Baptist Medical Center shows that radiologists can accurately detect breast cancer using digital mammography technology as effectively as traditional film-based methods. The technology has the potential to improve detection rates and reduce deaths from breast cancer.
Researchers are testing whether digitally enhanced mammograms can help detect breast cancer earlier, with a goal of improving radiologists' performance and enabling general radiologists to perform as well as specialized radiologists. The trial involves enhancing images from about 450 mammogram cases in a national database.
A study found that the ability to read mammograms varies significantly among general radiologists, with scores ranging from 8% to 98%. The experts detected more cancers but were also more likely to flag normal cases as abnormal.
A new study by Thomas Jefferson University finds that traditional criteria for stroke-preventing surgery may overestimate men's risk and underestimate women's risk due to smaller carotid arteries. The 70% blockage threshold may need to be adjusted to account for these differences.
A new digital X-ray technology being studied at Thomas Jefferson University Hospital has the potential to replace film-based radiography, reducing healthcare costs and improving patient care. The technology offers enhanced image quality, lower radiation doses, and increased efficiency for radiologists.
A new device has been developed to protect patients from radiation exposure during CT scans, with significant reductions in breast and thyroid radiation exposure reported. The reusable protective garment is expected to cost less than $30, making it a potential game-changer for individuals at risk of increased lifetime breast cancer risk.
Primary care physicians in high-managed care states saw rapid income growth, while specialist incomes lagged. Specialist incomes, especially for radiologists, anesthesiologists, and pathologists, increased most rapidly in low-managed care growth states.
A new type of MRI scan called dynamic kinematic MRI imaging has been shown to accurately diagnose joint problems, including knee, ankle, and temporomandibular joint issues. This technology allows doctors to pinpoint the exact point in range of motion where the problem occurs, enabling more precise diagnoses and treatment options.
