Which imaging technique uses a magnetic field to produce images?
A) CT
B) MRI
C) Both A and B
D) None of the above
B) MRI uses a magnetic field to produce images.
Which imaging technique is quick and less expensive?
A) CT
B) MRI
C) Both A and B
D) None of the above
A) CT is quick and less expensive than MRI.
Which imaging technique is more suitable for evaluating soft tissue injury and spinal cord injuries?
A) CT
B) MRI
C) Both A and B
D) None of the above
B) MRI is more suitable for evaluating soft tissue injury and spinal cord injuries.
Which imaging technique is more suitable for detecting trauma injuries, bleeding, and staging of cancer?
A) CT
B) MRI
C) Both A and B
D) None of the above
A) CT is more suitable for detecting trauma injuries, bleeding, and staging of cancer.
Which imaging technique may be contraindicated for patients with metal implants, tattoos, or obesity?
A) CT
B) MRI
C) Both A and B
D) None of the above
C) Both CT and MRI may be contraindicated for patients with metal implants, tattoos, or obesity, but for different reasons. MRI may be contraindicated due to metal implants or tattoos causing artifacts, while CT may be contraindicated due to the equipment not accommodating larger patients.
Which of the following is a disadvantage of using computed tomography (CT) imaging?
A) Can cause allergic reactions to contrast materials
B) Can only be used on patients who are not pregnant or possibly pregnant
C) Provides unlimited monitoring capabilities during imaging
D) Is not limited by the size of the patient
A) Can cause allergic reactions to contrast materials. One of the disadvantages of using CT imaging is that patients may have an allergic reaction to the contrast materials used to enhance the images. CT also exposes patients to excessive radiation, which can be a concern for repeat imaging. It is limited for pregnant or possibly pregnant patients due to the potential risk to the fetus. Transportation of critical patients can also be difficult due to the size and weight of the equipment. CT is limited in size and may not accommodate larger patients. Patient movement and artifacts can also be problematic, and CT does not provide unlimited monitoring capabilities during imaging.
Which of the following is an advantage of using computed tomography (CT) imaging over magnetic resonance imaging (MRI)?
A) Can image soft tissue with higher resolution
B) Can be used to measure and evaluate blood flow
C) Is not affected by implanted devices
D) Is less expensive and widely available
C) Is not affected by implanted devices. One of the advantages of using CT imaging is that it can be used on patients with implanted devices, such as pacemakers or artificial joints. CT can image bone, tissue, and blood vessels simultaneously, provide real-time imaging, and is cost-effective. However, CT is not as sensitive to soft tissue as MRI, which is known for its high-resolution imaging of soft tissues.
What is the primary purpose of using imaging techniques such as CT or MRI in medical settings?
A) To diagnose and treat infections
B) To detect and monitor internal injuries
C) To measure and evaluate blood flow
D) To evaluate and treat skin conditions
B) To detect and monitor internal injuries. Imaging techniques such as CT or MRI are often used to detect and monitor internal injuries, guide biopsies and drainages, plan for and assess the results of surgery, stage and plan radiation treatment, and monitor response to chemotherapy.
What is a common radiological finding in atelectasis?
a) Decreased density or opacity on the affected side
b) Increased density or opacity on the affected side
c) No change in density or opacity on the affected side
d) Increased lung markings in the affected area
b) Increased density or opacity on the affected side
What is a possible result of atelectasis on the mediastinum?
a) Displacement toward the affected side
b) Displacement away from the affected side
c) No displacement
d) No effect on the mediastinum
a) Displacement toward the affected side
What is a radiological finding in pneumothorax?
a) Increased lung markings in the affected area
b) Absence of lung markings in the pleural space
c) Decreased density or opacity on the affected side
d) Presence of lung markings in the pleural space
b) Absence of lung markings in the pleural space
What is the border seen on a chest x-ray in pneumothorax?
a) Visceral and parietal pleurae
b) Costophrenic angle
c) Mediastinum
d) Diaphragm
a) Visceral and parietal pleurae
What is a radiological finding in hyperinflation?
a) Decreased size of the lungs
b) Flattening of the heart shadow
c) Narrowing of the intercostal spaces
d) Widening of the intercostal spaces
d) Widening of the intercostal spaces
What is a radiological finding in congestive heart failure?
a) Decreased heart size
b) Absence of vascular congestion
c) Fluid accumulation in the interstitial spaces and alveoli
d) Clear lung fields
c) Fluid accumulation in the interstitial spaces and alveoli
What may be present in congestive heart failure?
a) Pleural thickening
b) Bronchial wall thickening
c) Pulmonary nodules
d) Pleural effusions
d) Pleural effusions
What is a radiological finding in pleural effusion?
a) Blunting or rounding of the costophrenic angle
b) Increased lung markings in the affected area
c) Absence of lung markings in the pleural space
d) Displacement of the mediastinum toward the affected side
a) Blunting or rounding of the costophrenic angle
What is the amount and distribution of the effusion in pleural effusion dependent on?
a) The age of the patient
b) The cause and severity of the effusion
c) The location of the effusion
d) The time of day
b) The cause and severity of the effusion
What is the hallmark of ARDS on radiological examination?
a. Widespread patchy opacities throughout both lungs
b. Absence of lung markings and displacement of the mediastinum
c. Increased density or opacity of the affected lung field and blunted costophrenic angle
d. Patchy or lobar distribution of increased density or opacity.
Widespread patchy opacities throughout both lungs are the hallmark of ARDS on radiological examination.
What are the common radiological findings for atelectasis?
An area of increased density or opacity on the affected side with loss of volume and displacement of the mediastinum toward the affected side.
What is the most common cause of atelectasis?
Obstruction of the bronchus or bronchiole, which may be due to mucus, a foreign body, or a tumor.
What is the radiological finding for pneumothorax?
Absence of lung markings in the pleural space, resulting in a dark area.
What is the line seen at the border of the collapsed lung?
It represents the visceral and parietal pleurae.
