Nokea
The patient has just had an MRI ordered because a routine chest x-ray showed suspicious areas in the right lung. The physician suspects bronchogenic carcinoma. An MRI would most likely be ordered to assess for what in this patient?
Correct Answer: D
Rationale: The correct answer is D: Chest wall invasion. An MRI would be ordered to assess for any potential invasion of the chest wall by the suspected bronchogenic carcinoma. MRI provides detailed imaging of soft tissues and can help determine the extent of tumor invasion beyond the lungs.
Explanation:
A: Alveolar dysfunction - Alveolar dysfunction is typically assessed using pulmonary function tests or imaging techniques like CT scans, not MRI.
B: Forced vital capacity - Forced vital capacity is a measure of lung function and is not typically assessed using MRI.
C: Tidal volume - Tidal volume is a measure of the volume of air moved in and out of the lungs during normal breathing and is not assessed using MRI in this context.
