Introduction to Radiology for Physician Assistants

Introduction to Radiology for Physician Assistants

Updated: 06/09/2016

In this post, I hope to introduce you all to the differences between imaging modalities, including indications and contraindications. My goal is also to provide a basic understanding of the concepts surrounding density and normal x-ray findings. Future posts will investigate the findings for pneumonia, pneumothoraces, effusions, atelectasis, fractures/dislocations, arthritis, intracranial, GI and hepatic pathology, bowel, lines/tubes, and heart disease.

Conventional Radiography (Plain Films)

• Images produced through use of ionizing radiation
• No contrast material (barium or iodine)
• Why it’s important: Large doses of radiation can produce cell mutations leading to cancer or anomalies. Even low levels of radiation are teratogenic (avoid in pregnancy).
• Relatively inexpensive, obtained easily (portable, mobile), most widely used
• Common uses: chest x-ray (CXR), abdominal x-ray, and for fractures or arthritis

Computed Tomography (CT or CAT Scans)

• Uses a gantry with a rotating x-ray beam and multiple detectors with sophisticated algorithms to process the data
• Expensive equipment, lots of space, and high computer processing power required

2015 PANCE Updates

2015 PANCE Updates

Because of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) publication, NCCPA will adapt its content blueprints, disease and disorder lists, and psychiatry-related terminology within test questions to conform to DSM-5 classifications and diagnostic criteria for all of our examinations beginning in 2015, according to the following timeline:

PANCE and PANRE administered in 2015:

In these examinations, psychiatry-related terminology within test questions will include the DSM-5 terminology followed by the DSM-IV-TR terminology in parentheses. Example: illness anxiety disorder (hypochondriasis)

PANCE and PANRE administered in 2016 and beyond:

In these examinations, only the DSM-5 terminology will be provided when appropriate. Example: illness anxiety disorder

Please also review the 2015 Content Blueprint Organ Areas and make sure you are studying with emphasis on those areas with most content. Remember, psychiatry is 6% of the PANCE!
