Children versus Adults – Who is more sensitive to radiation?

Almost all parents at some point during their children’s lives will need to take their child to the hospital for some sort of illness. Whether it is a cough, fever, broken bone, or abdominal pain, a visit to the emergency room or urgent care will include some sort of radiology study and often that radiology … Continue reading

Radiation Levels of Medical Imaging Studies

Imaging Modalities Medical imaging is a very broad area of medicine and includes many different types of imaging modalities. These include most commonly radiography (x-ray), nuclear medicine, magnetic resonance imaging (MRI), ultrasound, elastography, tomography, positron emitted tomography (PET) and computed tomography (CT), and echocardiography. Other more advanced or exotic imaging studies include photoacoustic imaging and … Continue reading

What is Radiation?

As a pediatric radiologist I have to be constantly aware of the radiation exposure I may be giving to my patients in my daily practice. Children are more sensitive to the effects of radiation, and they have a longer life to live to experience the potential sequelae of too much radiation. But radiation is also … Continue reading

Using Ionizing Radiation in Children – What do you know?

I’m curious to understand what the readers of know about ionizing radiation, so I’ve created a few questions that I’d like to get your answers to below.

Radiology Physics – Radionuclides

As a third installment in a series of articles on radiology physics, I’ve included a good summary table of important radionuclides to know for the ABR Core examination. This test also contains a component of the Radioisotope Safety Examination (RISE) which must be passed to obtain an Authorized User status from the ABR. Part of the … Continue reading

Radiology Physics – Acute Radiation Syndromes

In continuation of a series of posts on radiology physics as preparation for the ABR Core Examination, another important set of threshold doses to consider are those for acute radiation syndromes. Acute Radiation Syndrome (ARS), or radiation sickness, is a serious illness that can happen when a person is exposed to very high levels of radiation, … Continue reading
