Imaging Techniques

Question 1

X-ray

Answer 1

Basic diagnostic tool for bones, lungs, and certain soft tissues.

Question 2

CT (Computed Tomography)

Answer 2

Used for detailed cross-sectional images of the body, often for trauma, cancer, and internal organ issues.

Question 3

Ultrasound

Answer 3

Commonly used for soft tissue imaging, organ evaluation, pregnancy monitoring, and guiding procedures.

Question 4

MRI (magnetic resonance imaging)

Answer 4

Provides detailed images of soft tissues, brain, spinal cord, and joints.

Question 5

Fluoroscopy

Answer 5

Real-time imaging used during procedures like catheter placement, GI exams, and orthopedic surgery.

Question 6

ECG (Electrocardiogram)

Answer 6

Measures the heart’s electrical activity (with electrodes), essential for diagnosing heart conditions.

Question 7

Echocardiography

Answer 7

Ultrasound of the heart, used to assess heart structure and function.

Question 8

Angiography

Answer 8

Imaging of blood vessels using contrast dye, often used to diagnose and treat vascular diseases.

Question 9

Cardiac MRI

Answer 9

Specialized MRI for detailed heart imaging.

Question 10

Doppler Ultrasound

Answer 10

Assesses blood flow and detects blockages in blood vessels.

Question 11

PET (Positron Emission Tomography)

Answer 11

Used for cancer detection, cardiac function, and brain activity.

Question 12

SPECT (Single-Photon Emission Computed Tomography)

Answer 12

Provides 3D images of how blood flows to tissues and organs.

Question 13

fMRI (Functional MRI)

Answer 13

Measures brain activity by detecting changes in blood flow, used mainly in neurological research.

Question 14

Nuclear Medicine Imaging

Answer 14

Uses small amounts of radioactive materials to diagnose and treat diseases, including cancer and heart disease.

Question 15

Bone Densitometry (DEXA Scan)

Answer 15

Measures bone density, primarily used for diagnosing osteoporosis.

Question 16

EEG (Electroencephalography)

Answer 16

Records electrical activity in the brain, used to diagnose epilepsy and other brain disorders.

Question 17

MEG (Magnetoencephalography)

Answer 17

Measures magnetic fields from brain activity, sometimes studied in neurology

Question 18

Cerebral Angiography

Answer 18

Specialized angiography for visualizing blood vessels in the brain.

Question 19

Diffusion Tensor Imaging (DTI)

Answer 19

A form of MRI that maps white matter tracts in the brain, useful in stroke and brain injury cases.

Question 20

Mammography

Answer 20

X-ray of the breast for cancer screening.

Question 21

Interventional Radiology

Answer 21

Uses imaging guidance (e.g., fluoroscopy, ultrasound, CT) to perform minimally invasive procedures like biopsies or stent placements.

Question 22

Contrast Studies (e.g., Barium Swallow):

Answer 22

X-ray studies enhanced with contrast agents to visualize the GI tract.

Question 23

Resting-State fMRI

Answer 23

Studies spontaneous brain activity in the absence of a specific task, often in research.

Question 24

Perfusion imaging

Answer 24

Measures blood flow, particularly in the brain or heart, used to detect strokes or heart disease.

Question 25

PQR are typically referred to with what imaging technique?

Answer 25

ECG

Question 26

P wave function? Conditions?

Answer 26

-shows when top part of heart (atria) is squeezing to push blood into lower part. First thing that happens in a heartbeat.

-Atrial enlargement, fibrillation, arrhythmias, and tachycardia

Question 27

QRS function? Conditions?

Answer 27

-shows when bottom part of heart (ventricles) is squeezing to pump blood out to your body.

-Q Wave: A small dip before the main squeeze. Downward depolarization
• R Wave: The big spike, showing the main squeeze of your heart. Ventricular depolarization
• S Wave: A small dip right after the big spike, showing the end of the squeeze. final depolarization of the ventricles.

• ventricular hypertrophy (thickened ventricular walls), bundle branch blocks (delays in electrical conduction), or heart attacks (myocardial infarction).

Question 28

R wave function? Conditions?

Answer 28

prominent upward spike in the QRS complex and represents the rapid depolarization of the ventricles, particularly the left ventricle, which is responsible for pumping oxygenated blood to the body.

-can indicate heart strength, ventricular size, and conduction issues (electrical problems)—>such as bundle branch block
