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

Radiology Physics – Radioactive Material Package Labels

Packages that arrive to a nuclear medicine┬ádepartment may be labeled with special radioactive labels that have specific allowable limits of radiation depending on the label. As part of the radioisotope safety examination, candidates should be aware of what these labels mean. The captions of each label below have the specific amounts of radiation that each … Continue reading

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┬átest 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

Paget’s Disease

History: 60 year old male with hip pain. The differential diagnosis for this appearance on a Tc-99m MDP bone scan includes fibrous dysplasia, Paget’s disease, bone metastases, and primary bone tumor. This is a case of Paget’s disease. Paget’s disease is a disorder of abnormal and excessive bone remodeling, which results in deformed and weakened … Continue reading

Metastatic Malignant Mesothelioma

History: 60 year old male with left sided chest pain. This is a case of pathology proven metastatic malignant mesothelioma. These are tumors of the pleura, and are most likely secondary to long-term asbestos exposure, in which there is a dose-response relationship and typically a latent period of 30-45 years. Asbestos plaques are not a … Continue reading

Parathyroid Adenoma

History: 50 year old female with a history of hypercalcemia. The patient went on to receive a CT scan of the neck with contrast which revealed an enhancing nodule posterior to the inferior right thyroid lobe, which was excised and confirmed on pathology to be a parathyroid adenoma. Hyperparathyroidism was the etiology of the patient’s … Continue reading
