New study finds many healthcare providers underestimate actual radiation dose from CT scans

Computed tomography (CT) scans are an invaluable diagnostic tool in modern medicine, but they do come at a price: exposing patients to potentially dangerous ionizing radiation. [More]
Many family doctors have poor knowledge about LDCT lung cancer screening

Many family doctors have poor knowledge about LDCT lung cancer screening

Although clinical trials have shown that lung cancer screening using low-dose computed tomography (LDCT) can detect lung cancers early and reduce lung cancer mortality, less than half of family physicians in a recent survey agreed that screening reduces lung cancer–related deaths. [More]

Advanced imaging kit Netspot gets FDA approval to detect rare neuroendocrine tumors

The U.S. Food and Drug Administration today approved Netspot, the first kit for the preparation of gallium Ga 68 dotatate injection, a radioactive diagnostic agent for positron emission tomography (PET) imaging. [More]
New drugs show promise as first antidote for radiation exposure

New drugs show promise as first antidote for radiation exposure

University of Virginia School of Medicine researchers have identified promising drugs that could lead to the first antidote for radiation exposure that might result from a dirty bomb terror attack or a nuclear accident such as Chernobyl. [More]
Axumin approved for use in PET scans in patients with recurrent prostate cancer

Axumin approved for use in PET scans in patients with recurrent prostate cancer

The U.S. Food and Drug Administration today approved Axumin, a radioactive diagnostic agent for injection. Axumin is indicated for positron emission tomography (PET) imaging in men with suspected prostate cancer recurrence based on elevated prostate specific antigen (PSA) levels following prior treatment.

Continuous errors in damaged DNA repair may lead to tumor formation

Continuous errors in damaged DNA repair may lead to tumor formation

A group of researchers at Osaka University found that if DNA damage response (DDR) does not work when DNA is damaged by radiation, proteins which should be removed remain instead, and a loss of genetic information can be incited, which, when repaired incorrectly, will lead to the tumor formation.

New Rutgers research aims at exploring gender differences in lung cancer

New Rutgers research aims at exploring gender differences in lung cancer

Lung cancer is the leading cause of cancer death in both men and women. Lung cancer diagnoses have more than doubled among females in the past 38 years, while having fallen 29 percent among males, according to the American Lung Association. [More]
Conventional repeated radiation treatments may offer no major benefit to brain tumor patients

Conventional repeated radiation treatments may offer no major benefit to brain tumor patients

A new study shows that repeated radiation therapy used to target tumors in the brain may not be as safe to healthy brain cells as previously assumed. [More]
Ga-68 DOTATATE PET/CT scans more effective than current imaging standard for detecting NETS

Ga-68 DOTATATE PET/CT scans more effective than current imaging standard for detecting NETS

A recent study reported in the May issue of the Journal of Nuclear Medicine demonstrates that Ga-68 DOTATATE PET/CT scans are superior to In-111 pentetreotide scans, the current imaging standard in the United States for detecting neuroendocrine tumors, and could significantly impact treatment management.

Robotically assisted PCI could be viable alternative to manual procedure

Robotically assisted PCI could be viable alternative to manual procedure

A first-of-its kind study using robotic technology to remotely control coronary guidewires and stents reported on the feasibility of performing percutaneous coronary intervention (PCI) on patients with complex coronary lesions. Similar clinical outcomes compared to the PCI procedure performed manually were reported. [More]
Innovative bone marrow-on-a-chip microdevice holds promise for developing improved radiation countermeasures

Innovative bone marrow-on-a-chip microdevice holds promise for developing improved radiation countermeasures

Engineered bone marrow grown in a novel microfluidic chip device responds to damaging radiation exposure followed by treatment with compounds that aid in blood cell recovery in a way that mimics living bone marrow. [More]
Single dose of intraoperative radiotherapy effective for early stage breast cancer patients

Single dose of intraoperative radiotherapy effective for early stage breast cancer patients

In the South East of England, a patient experience study of 18 early stage breast cancer patients who opted for single dose intraoperative radiotherapy, found positive patient reported outcomes for this alternative to standard daily external beam radiotherapy. [More]
Simple blood test can help detect evidence of concussions up to 7 days after injury

Simple blood test can help detect evidence of concussions up to 7 days after injury

Researchers at Orlando Health detected evidence of concussions in patients up to 7 days after their injury using a simple blood test, according to a new study published in JAMA Neurology. The discovery could greatly expand the window for diagnosing concussions, especially in patients who experience a delayed onset of symptoms. [More]
Annual LDCT screenings not required for most high-risk lung cancer patients

Annual LDCT screenings not required for most high-risk lung cancer patients

Most high-risk lung cancer patients might not need annual low-dose computed tomography (LDCT) screenings if they are cleared of disease in their initial test, according to a study led by a Duke Cancer Institute researcher. [More]

Low levels of radiation exposure does not affect health, study finds

Researchers in Europe have reviewed cancer rates among people in parts of the world where natural background radiation is higher than average and found that incidence is not as high as one might guess. The findings, published in the International Journal of Low Radiation suggests that science ought to take a second look at studies that correlate low levels of radiation exposure with detrimental health effects [More]
New blood test may potentially facilitate detection of Alzheimer's disease at early stage

New blood test may potentially facilitate detection of Alzheimer's disease at early stage

Today, Alzheimer's disease is diagnosed too late. In collaboration with a research team at the university and German Center for Neurogenerative Diseases in Göttingen, Researchers at Ruhr-Universität Bochum have developed a blood test that may potentially facilitate detection of Alzheimer's at an early stage. It is based on an immuno-chemical analysis using an infrared sensor. [More]
Researchers exploring ways to prevent radiation-induced cancer risk in astronauts

Researchers exploring ways to prevent radiation-induced cancer risk in astronauts

NASA limits an astronaut's radiation exposures to doses that keep their added risk of fatal cancer below 3 percent. Unfortunately, that ceiling restricts the time an astronaut may spend in space, which in turn restricts the ability to perform longer missions, say a mission to Mars. [More]
NYU Langone Medical Center researchers successfully perform CT scans for joint fractures

NYU Langone Medical Center researchers successfully perform CT scans for joint fractures

Computed Tomography (CT) scans are one of the most frequently used imaging tools in medicine. In fact, more than 72 million scans are performed each year to diagnose various medical conditions. But public health concerns persist about radiation exposure from these tests—especially when given to children and young adults. [More]
Low-dose EOS performs as well as conventional CT scans in assessing limb length, finds HSS study

Low-dose EOS performs as well as conventional CT scans in assessing limb length, finds HSS study

When a child needs repeated x-rays, exposure to radiation is always a concern for parents. A new study at Hospital for Special Surgery finds that a relatively new imaging system known as EOS, which provides less radiation exposure, performed as well as conventional CT scans in assessing limb length.
