Phase 2 trial data of PET myocardial perfusion imaging with flurpiridaz F 18 presented at ICNC10

Lantheus Medical Imaging, Inc., a worldwide leader in diagnostic imaging, today announced data from a Phase 2 clinical trial that demonstrated Positron Emission Tomography myocardial perfusion imaging with flurpiridaz F 18 provided superior image quality, diagnostic certainty and diagnostic performance for detecting coronary artery disease (CAD) compared to single photon emission computed tomography myocardial perfusion imaging, the current standard for the non-invasive detection of CAD.

Bedside screening tool can help diagnose acute aortic dissection

The most lethal and sudden cardiovascular event can be the toughest for doctors to diagnose. But a study by the University of Michigan Cardiovascular Center shows new guidelines are effective for determining who's most likely suffering from an aortic dissection, which is tearing in the lining of the body's largest blood vessel.

Researchers identify miRNA in blood serum of lung cancer patients

Researchers have identified characteristic patterns of molecules called microRNA in the blood of people with lung cancer that might reveal both the presence and aggressiveness of the disease, and perhaps who is at risk of developing it.

Pelvic imaging using CT exams are not necessary for VTE diagnosis

A recent study shows that pelvic imaging using computed tomography examinations are not necessary for diagnosing patients with venous thromboembolism and eliminating this exam can significantly reduce a patient's exposure to excessive radiation dose.

NCRP workshop on CT use in emergency medicine is now available through JACR May issue

A summary of the National Council on Radiation Protection's workshop on the appropriate use of computed tomography in emergency medicine, and a list of recommendations from participating organizations to help control the inappropriate use of CT in the emergency department, is now available via the May issue of the Journal of the American College of Radiology.

No proven advantages of PET for diagnostic accuracy of head and neck tumours: Research

The benefit and harm of positron emission tomography in patients with head and neck tumours, applied alone or in combination with computed tomography, cannot currently be reliably assessed.

New nanoparticle imaging agent can help diagnose heart disease, breast cancer

Scientists are reporting development of a process for producing large quantities of a much-needed new imaging agent for computed tomography scans in heart disease, breast cancer and other diseases, and the first evidence that the material is safe for clinical use.

Study finds substantial increase in pediatric CT in hospital emergency departments

Computed tomography examinations of children in hospital emergency departments increased substantially from 1995 to 2008, according to a new study published online and in the June print edition of Radiology. Researchers said the findings underscore the need for collaboration among medical professionals to ensure that pediatric CT is appropriately ordered, performed and interpreted.

New method allows lowest possible dose of radiation for children undergoing CT scans

A research team at the Queen Silvia Children's Hospital has developed a method that allows the lowest possible dose of radiation for children having a CT scan while still obtaining good image quality, reveals a thesis from the Sahlgrenska Academy.

Regular CT scans can cause secondary malignancies in older men with testicular cancer

UC Davis cancer researchers have found that older men with early-stage testicular cancer who opt for surveillance with regular CT scans over lymph node removal are at greater risk for secondary cancers.

New research measures direct radiation doses in patients during endovascular procedures

New research published in the April 2011 issue of the Journal of Vascular Surgery®, the official publication of the Society for Vascular Surgery®, directly measured the radiation doses for patients and operators during complex endovascular procedures.

Prostatic artery embolization comparable to transurethral resection

A new interventional radiology treatment that blocks blood supply to men's enlarged prostate glands shows comparable clinical results to transurethral resection of the prostate (or TURP), considered the gold standard (or most common) treatment. However, this minimally invasive treatment-prostatic artery embolization-has none of the risks associated with TURP, such as sexual dysfunction, urinary incontinence, blood loss and retrograde ejaculation, noted researchers at the Society of Interventional Radiology's 36th Annual Scientific Meeting in Chicago.

Hydro-stomach CT imaging is not a reliable tool for EGC detection: Study

Traditionally, both air and tap water have been used as oral contrast agents to achieve adequate gastric distension for preoperative computed tomography imaging in patients with early gastric cancer.

EMP levels may help clinicians diagnose early emphysema

Monitoring blood for tiny particles released by cells lining the lungs may help clinicians diagnose emphysema in its earliest stages, according to researchers from Weill Cornell Medical College. The particles, called endothelial microparticles, are shed during the disease process as tiny blood vessels in the lungs, called pulmonary capillaries, are injured and die.

Understand radiology benefits and risks before undergoing scans: ACR

As part of Patient Safety Awareness Week, the American College of Radiology (ACR) reminds patients that everyone should understand radiology benefits and risks before they or a loved one receives an X-ray, computed tomography (CT) scan or other medical imaging exam.
