What is the focus of chiropractic radiology training?

Musculoskeletal (MSK) radiology.

How many years of residency is required for chiropractic radiologists?

A minimum of 3 years after obtaining a Doctor of Chiropractic degree.

What are the two exams required for chiropractic radiologist certification?

Core written exam and certifying practical exam.

What is a radiographer?

A professional who performs diagnostic imaging procedures using radiation-emitting equipment.

What does PACS stand for in medical imaging?

Picture Archiving and Communication System.

What are the effects of ALARA?

As Low As Reasonably Achievable principles for radiation exposure.

What does the ACR do for its members?

Empowers members to deliver exceptional patient care through advocacy, quality and safety.

What must a diagnostic imaging requisition form include?

Patient name, diagnosis, physician signature, and requested exam type.

What must be documented in a radiology report's impression section?

A specific diagnosis, differential diagnosis, and recommendations for follow-up.

What are the components of a diagnostic imaging report?

Demographics, clinical information, body of the report, impression, recommendations.

What does sensitivity refer to in diagnostic testing?

The ability of a test to correctly identify patients with the disease.

What is specificity in the context of diagnostic tests?

The ability of a test to correctly identify patients without the disease.

What term is used to refer to a static image produced by X-rays?

Radiograph.

What is true positive in diagnostic testing?

A test result indicating disease when the disease is indeed present.

What is a false negative result?

A test result indicating no disease when the disease is actually present.

What is the importance of documenting findings in a radiology report?

To provide a permanent record, facilitate communication, and assist in patient care.

What is the recommended approach for writing radiology reports?

Systematic and structured, including steps like alignment, bone, cartilage, and soft tissue.

What imaging modality uses ionizing radiation?

Radiography (X-rays).

Which type of imaging provides real-time imaging for procedures?

Ultrasound.

How does MRI differ from CT in terms of soft tissue visualization?

MRI provides better soft tissue contrast than CT.

What is the purpose of DICOM in medical imaging?

Facilitates the storage and transmission of medical images.

What is core purpose of the American College of Radiology?

To serve patients and society by advancing the practice and science of radiologic care.

What principle is associated with minimizing time, distance, and shielding in radiation exposure?

ALARA principle.

What kind of imaging is often preferred for assessing joint health?

MRI due to its ability to assess soft tissues.

Summary of findings and recommendations for follow-up.

What criteria must be met for imaging procedures to be justified?

1. Increase information, 2. Alter prognosis or management, 3. Weigh benefits against hazards, 4. Be more useful than less invasive alternatives.

What is an example of an imaging procedure that must be scheduled?

MRI or Ultrasound.

What does NPV stand for in diagnostic metrics?

Negative Predictive Value, the probability that a negative test result is accurate.
