Webster Center takes on radiation-dose reduction

Dr. James H. Thrall, Department of Radiology chairman emeritus, discusses The Webster Center for Advanced Research and Education in Radiation, a unique research effort dedicated to reducing radiation dose for every exam Mass General Imaging performs.

Radiation reduction: Our ongoing commitment

As CT (computed tomography) technology has transformed the practice of medicine, Mass General Imaging has dedicated itself to making sure each exam exposes the patient to the lowest achievable amount of radiation. Department of Radiology Chairman Emeritus James H. Thrall, MD, discusses our decade-long commitment—and our success—regarding this issue.

Decision tools support radiation-reduction efforts

One effective way to reduce radiation exposure is to avoid unnecessary exams. That's why Mass General Imaging has been a leader in developing software tools that guide referring physicians by not only making sure the selected exam matches the patient's needs but also suggesting radiation-free alternatives when appropriate.

Imaging specialists, focused on you

Each radiologist at Mass General Imaging is a specialist in a particular area of the body. Department of Radiology Chairman Emeritus James H. Thrall, MD, explains how patients benefit from the additional specialty training our physicians have completed.

Imaging technology enables non-surgical treatments

Department of Radiology Chairman Emeritus James H. Thrall, MD, explains how the ability to see deep inside the body has driven the development of minimally invasive methods of treatment—a trend in which Mass General Imaging has played a key role.

Imaging research: Creating the cutting edge

Chairman Emeritus James H. Thrall, MD, describes the Department of Radiology's research efforts and how they translate into new imaging methods that in turn transform the practice of medicine.

Imaging research: Revolutionary results

Researchers in the Mass General Department of Radiology have made many revolutionary discoveries and are hard at work on many more. Chairman Emeritus James H. Thrall, MD, discusses two prominent examples: functional MRI and molecular imaging.

Training the next generation of specialized radiologists

Education is central to the mission of the Department of Radiology. Chairman Emeritus James H. Thrall, MD, explains that the organization takes its commitment to training future radiologists very seriously, and values the contributions residents and fellows make during their time at Mass General.

The radiation risk from full-body scanners used to improve airport security is low and unlikely to raise an individual's risk of cancer, according to experts including Mass General's Dr. James Thrall.

Q&A: Look closer at CT scan cancer risks

In many cases, the benefits of these tests—in finding cancers, aneurysms or blood clots—far outweigh the relatively low risks of radiation.

Study looks at radiation exposure

As many as two-thirds of adults underwent a medical test in the last few years that exposed them to radiation and in some cases, a potentially higher risk of cancer, a study in five areas of the US suggests.
