Contrast-enhanced MRI is a reliable method to measure blood flow to tumors, allowing for accurate assessment of chemotherapy response and tumor viability. The study found that patients who responded to treatment had significant decreases in angiogenesis, while non-responders showed increases.
A new study found that combining radiofrequency ablation with chemotherapy can effectively treat larger liver tumors. The treatment, which involves using heat to destroy tumor tissue and administering a chemotherapeutic agent intravenously, resulted in a tripling of survival rates compared to those receiving no treatment.
Chemoembolization is the treatment of choice for widespread or diffuse tumors, enabling patients with primary liver cancer to live longer and maintain a quality of life. The procedure uses oil droplets to transport chemotherapy agents directly to the tumor, reducing toxicity and improving outcomes.
New technologies, such as robotics and GPS-guided therapy, are being integrated with imaging technology to enhance precision in minimally invasive procedures. These advancements aim to reduce human error and improve patient outcomes.
Detachable coil embolization is a new approach to treating brain aneurysms, offering less invasive treatment with shorter recovery times. The procedure has been shown to reduce mortality rates by 22.6% compared to traditional open surgery for patients with ruptured aneurysms.
A survey of US radiology residents found that most were hesitant to pursue breast imaging training or interpret mammograms due to negative attitudes and perceived drawbacks. The shortage of qualified radiologists is expected to worsen as demand for screening mammography services increases with an aging population.
A study conducted at Lausanne University Hospital found that MDCT accurately depicted more spine fractures than conventional x-rays, with a sensitivity rate of nearly three times higher. This innovation could save time, money, and radiation exposure for patients admitted to emergency departments for severe trauma.
A study of 73 patients with symptoms suggestive of SARS found that CT scans identified three common features: ground-glass opacification, lower lobe distribution, and peripheral distribution. These findings suggest that CT can be a valuable diagnostic tool for detecting SARS, particularly in cases where chest x-rays are normal.
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.
