    Radiation that is scattered or created as a result of the attenuation of the primary x-ray beam by matter.

    • Scatter radiation fog

    • Radiation field

    • Scatter radiation

    • Latent image

    Correct Answer
    A. Scatter radiation
    Explanation
    Scatter radiation refers to the radiation that is scattered or created when the primary x-ray beam is attenuated by matter. This means that when the primary x-ray beam interacts with an object, some of the radiation is scattered in different directions. Scatter radiation can cause a phenomenon known as scatter radiation fog, which can reduce image quality and clarity. Therefore, the correct answer is scatter radiation.

    3)   The following indications are for which of the following modalities: Obstructive jaundice,Neoplastic biliary stricture, spincter of oddi pressure.   a. MRA   b. ERCP   c. EGD  

    • A

    • B

    • C

    Correct Answer
    A. B
    Explanation
    The correct answer is B) ERCP. ERCP (Endoscopic Retrograde Cholangiopancreatography) is a procedure used to diagnose and treat conditions of the bile ducts and pancreas. It is commonly used to investigate and treat obstructive jaundice and neoplastic biliary strictures by visualizing the biliary system and obtaining tissue samples. It can also measure the pressure of the sphincter of Oddi, which is the muscle that controls the flow of bile and pancreatic juices into the small intestine. MRA (Magnetic Resonance Angiography) and EGD (Esophagogastroduodenoscopy) are not indicated for these conditions.

    1)   This modality is used for bowel cleansing and requires sedation . CAN VISUALIZE ENTIRE LARGE BOWEL AND SEVERAL CM OF TERMINAL ILEUM   a. Colonoscopy   b. Sigmoidoscopy   c. Video capsule endoscopy      

    • A

    • B

    • C

    Correct Answer
    A. A
    Explanation
    Colonoscopy is the correct answer because it is a modality used for bowel cleansing and requires sedation. It allows visualization of the entire large bowel and several centimeters of the terminal ileum. Sigmoidoscopy only visualizes the sigmoid colon and rectum, while video capsule endoscopy involves swallowing a small camera to visualize the small intestine. Therefore, colonoscopy is the most appropriate option for visualizing the entire large bowel and terminal ileum.

    4)   This contrast study uses fluoroscopy and is used to detect esophageal rings, webs, strictures, motility problems that endoscopy might miss. Very useful for evaluating nonoropharangeal dysphagia as well as Odynophagia.   a. Barium Swallow/Esophagram   b. CT scan   c. Video Esophagram   d. None of the above

    • A

    • B

    • C

    • D

    Correct Answer
    A. A
    Explanation
    This question is asking for the correct test to detect esophageal rings, webs, strictures, and motility problems that endoscopy might miss. The given answer, A) Barium Swallow/Esophagram, is the correct option because this test uses fluoroscopy to visualize the esophagus and detect any abnormalities. It is particularly useful for evaluating nonoropharyngeal dysphagia (difficulty swallowing) and Odynophagia (painful swallowing). CT scan (B) and Video Esophagram (C) are not specifically used for this purpose, and option D) None of the above is incorrect because there is a specific test available for this condition.

    Absorbed dose is the energy deposited in a small volume of matter (tissue) by the radiation beam passing through the matter divided by the mass of the matter. What unit, in the International System of quantities and units, is Absorbed Dose measured in?

    • The gray

    • The rad

    • The sievert

    • The joule

    Correct Answer
    A. The gray
    Explanation
    Absorbed dose is measured in joules/kilogram, and a quantity of 1 joule/kilogram has the special unit of gray (Gy) in the International System of quantities and units. (In terms of the older system of radiation quantities and units previously used, 1 Gy equals 100 rad, or 1mGy equals 0.1 rad.)

    Which of the following features on mammogram would suggest malignancy?

    • Well defined lesion

    • A mass of decreased density

    • Areas of spiculated microcalcifications

    • Smooth borders

    Correct Answer
    A. Areas of spiculated microcalcifications
    Explanation
    Areas of spiculated microcalcifications on a mammogram suggest malignancy because they are a characteristic feature of breast cancer. Spiculated microcalcifications appear as small, irregular, and linear clusters of calcium deposits in the breast tissue. These calcifications can indicate the presence of a tumor or precancerous cells. The spiculated appearance indicates that the tumor or lesion has irregular and jagged borders, which is often associated with aggressive and invasive types of breast cancer. Therefore, the presence of spiculated microcalcifications is concerning for malignancy and warrants further evaluation.

    The lead diaphagm determines the size and shape of the

    • Electron cloud

    • Film used

    • Xray beam

    • All of the above

    Correct Answer
    A. Xray beam
    Explanation
    The lead diaphragm determines the size and shape of the x-ray beam. The lead diaphragm is a device that is used to control the size and shape of the x-ray beam by limiting the radiation to a specific area of the patient's body. By adjusting the position and size of the lead diaphragm, the radiographer can ensure that only the desired area is exposed to radiation, reducing unnecessary exposure to other parts of the body. Therefore, the lead diaphragm plays a crucial role in determining the size and shape of the x-ray beam.

    The x-ray beam that exits on the opposite side of the patient.

    • Radiation field

    • Scatter radiation fog

    • Scatter radiation

    • Remnant radiation

    Correct Answer
    A. Remnant radiation
    Explanation
    Remnant radiation refers to the x-ray beam that exits on the opposite side of the patient after passing through the body. This radiation is produced by the interaction of the x-rays with the patient's tissues. It is called "remnant" because it is the portion of the original x-ray beam that remains after being attenuated by the patient's body. This remnant radiation can contribute to scatter radiation, which is the scattered x-rays that can cause fogging on the radiographic image. Therefore, remnant radiation is the correct answer in this context.
