Long-term data from a study showed that abatacept treatment significantly slowed the progression of structural damage in rheumatoid arthritis patients who had an inadequate response to methotrexate. The effect was seen at year 2 and continued into the second year, suggesting progressive improvement.
A recent study found that extending localizer radiographs and extra axial images beyond defined levels increases radiation exposure. Limiting these areas can significantly reduce radiation dose while maintaining diagnostic quality. The researchers discovered that a total of 562 extra images were acquired in the studied examinations.
A study of 546 patients found that chest x-rays are not effective in determining when tuberculosis (TB) was acquired. The researchers discovered that the most significant independent predictor of radiographic appearance is HIV status, indicating altered immunity rather than recent infection.
The study found that patients with ankylosing spondylitis who took NSAIDs continuously experienced less spinal joint damage than those who only used them for pain management. This suggests that inflammation and progression of joint damage may be separate processes in AS, and NSAIDs may have unexplored disease-controlling properties.
A study found that 1 in 6 elderly patients with clinically important vertebral fractures had unreported osteoporosis diagnoses, highlighting the need for better screening and treatment strategies.
Researchers studied 590 patients aged 7-18 to develop a cephalometric radiograph score. Those with high scores were more likely to have higher RDI (respiratory disturbance index) scores, indicating potential sleep-disordered breathing risk. This pilot study suggests radiography may be used to identify teenagers at risk for sleep apnea.
A long-term study of 835 participants found moderate acetabular dysplasia to be a strong independent risk factor for hip OA. Women with acetabular dysplasia had a higher incidence and severity of hip OA, especially those with high-stress workloads and low BMI.
Researchers analyzed 4,369 chest radiographs from 313 SARS patients and found that lung opacification levels on the seventh day could predict fatal outcomes. Patients with greater than 20% lung opacification were more likely to die from SARS, while those with less than 10% had a higher survival rate.
Researchers found a strong correlation between a peptide fragment of type II collagen (CTX-II) and the prevalence and progression of osteoarthritis (OA), particularly at the knee and hip. CTX-II levels were associated with increased risk and severity of OA, including rapid joint destruction.
A study of 1,325 patients revealed that CT pulmonary angiograms expose female breasts to at least 2.0 rads per breast, equivalent to 10-25 mammograms or 100-400 chest radiographs. Researchers recommend reducing radiation exposure by selecting suitable patients, using alternative imaging methods, and manipulating scan parameters.
The study found that dedicated CT technology detected lower spine fractures in 36 patients, while plain radiographs only detected them in 28. Transverse process fractures were also identified more accurately on MDCT. The benefits of using MDCT include improved patient care and cost savings.
A population-based case control study found a significant association between exposure to diagnostic radiography during routine dental care and low birth weights in full-term babies. The study suggests that radiation may affect neurohormonal mechanisms in the head and neck region, leading to potential health effects on pregnancies.
A prospective study in Botswana found that only 1.8% of asymptomatic HIV-infected outpatients with preventive therapy developed TB, rendering routine chest radiography unnecessary for screening in settings where signs and symptoms can be effectively identified.
Eighty percent of patients treated with combination therapy experienced no radiographic progression, compared to 68% on ENBREL alone and 57% on methotrexate. Combination therapy and ENBREL monotherapy provided significant inhibition of joint damage.
A new study published in the Journal of the American Medical Association found that rapid MRI did not improve clinical outcomes or save money for patients with low back pain. In fact, it may increase costs due to an increased risk of surgical interventions.
A study reveals that CT scans are more effective than plain film radiography in diagnosing cervical spine trauma. The research found a higher incidence of true positive findings with CT (5.85%) compared to plain film (.50%), as well as lower costs due to reduced examination time.
The study found that physician judgment had a sensitivity of 89% and specificity of 26% for the Ottawa rules, and 80% and 59% for the Leiden rule. With structured data collection, physicians' judgment was similar to existing ankle rules in terms of sensitivity and ability to safely reduce radiographic examinations.
Researchers at Cornell University's Laboratory of Plasma Studies have developed a new X-pinch imaging technique that produces extremely high-resolution images of minute objects. The technique, which uses powerful electrical currents to create plasma, has been used to image objects as small as house fly hairs and even living ants.
A study found that miniature chest radiography is the most effective way to detect active tuberculosis in jails due to its efficiency and low radiation dose. This method can identify 200 cases per 100,000 inmates or higher, significantly higher than the general U.S. population rate of 6.8 cases per 100,000 persons.
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.
Researchers detected calcifications in the carotid arteries of 5% of new patients, with many having multiple risk factors for atherosclerosis. The findings suggest that routine dental X-rays could be a valuable tool in detecting patients at risk for stroke.
