DHA Computed Tomography - Why Exam Edge Sample Questions

All but which of the following would be considered a type of CT scan artifact?

Correct Answer:
pitch


ct (computed tomography) scans are invaluable diagnostic tools in the medical field, providing detailed cross-sectional images of the body. however, these images can sometimes be affected by artifacts, which are errors or distortions that compromise the quality and the accuracy of the scans. artifacts in ct scans can arise from a variety of sources including patient movement, machine errors, or physical properties of the scanned materials.

types of common ct scan artifacts include: 1. **beam hardening:** this occurs when lower energy photons are absorbed more than the higher energy photons as the x-ray beam passes through denser materials like bones. this can create streaks or dark bands in the image. 2. **noise:** this artifact appears as graininess in the image and is usually due to insufficient photon counts, which can be a result of low radiation dose or fast scanning. 3. **pseudoenhancement:** an increase in the apparent density of a structure, often seen in small structures surrounded by denser material. 4. **helical artifact:** seen in helical (or spiral) ct scanning, this can occur due to interpolation errors as the scanner constructs images from the continuously acquired data during tube rotation. 5. **cone beam artifact:** this arises in cone-beam ct scanners due to the geometric complexity of capturing data in a cone-shaped beam, leading to distortions especially at the edges of the scan field. 6. **motion artifact:** results from movement of the patient during scanning, causing blurring or streaking. 7. **metal artifact:** occurs due to the presence of metal in the scan field, which can cause streaking and dark areas due to the metal absorbing x-rays. 8. **scatter artifact:** caused by scatter radiation, which can increase noise and reduce the contrast in images. 9. **ring artifact:** typically arises from calibration errors or detector malfunctions in the scanner, appearing as concentric rings on the image.

on the other hand, "pitch" in the context of ct scanning does not refer to an artifact but to a technical parameter of the scan. pitch refers to the ratio of the table feed per rotation to the total width of the x-ray beam. the selection of pitch affects scan duration, image quality, and patient dose. a higher pitch can reduce scan time and radiation exposure, but might also reduce image quality, while a lower pitch generally improves image quality but increases exposure and scan time.

therefore, when asked which of the options is not a ct scan artifact, "pitch" is the correct answer. it is a scanning parameter rather than an artifact. understanding this distinction is crucial for optimizing ct scan protocols and managing the quality of images produced.

If the technologist is performing an abdominal CT scan on a blunt abdominal trauma patient, which of the following would they consider the most common site of organ trauma to be?

Correct Answer:
spleen
in the context of performing an abdominal ct scan on a patient with blunt abdominal trauma, the technologist must prioritize areas likely to be affected based on statistical frequency and clinical presentation. here is an expanded explanation of why the spleen is considered the most commonly injured organ in such cases:

blunt abdominal trauma refers to a physical impact to the stomach area without any penetrating injury, such as might occur in car accidents, falls, or sports injuries. this kind of trauma can cause significant damage to internal organs and blood vessels, leading to internal bleeding and other complications. the abdomen contains several vital organs, and the nature of the impact can result in varying patterns of injury.

among the organs in the abdominal cavity, the spleen is particularly susceptible to injury from blunt trauma. the spleen, located in the upper left part of the abdomen, acts primarily as a filter for blood as part of the immune system, helping to fight bacteria and manage the body's blood cells. its location and relatively fragile structure make it prone to damage when force is applied to the abdomen. the spleen's position just below the rib cage, where it can be compressed or impacted directly, contributes to its vulnerability.

when a technologist prepares to perform an abdominal ct scan on a trauma patient, recognizing the spleen as a common site of injury is crucial. this knowledge guides the scanning process, prompting a detailed evaluation of this area to assess any damage such as lacerations, ruptures, or internal bleeding. identifying spleen injuries is critical because they can lead to severe internal bleeding, which is a major cause of death in blunt abdominal trauma cases if not promptly diagnosed and treated.

the emphasis on the spleen over other organs such as the stomach, small intestines, or appendix arises from epidemiological data indicating that the spleen is more frequently involved in trauma-related injuries. while these other organs can certainly be affected, their structural characteristics and protective positioning within the abdominal cavity generally render them less susceptible to injury from blunt force compared to the spleen.

it is important for medical professionals, including technologists, to be aware of these injury patterns as they impact the approach to diagnosis and treatment. a thorough and focused ct scan can be a life-saving measure, enabling rapid intervention strategies such as surgical repair or conservative management depending on the extent of the injury. this level of vigilance and informed scanning not only improves outcomes but also aligns with best practices in emergency and trauma medicine.
