Question

Discuss what Proton MRI imaging of the lung is. Discuss the indication, advantages and disadvantages of using this technique when evaluating V/Q mismatch. Discuss how different pulmonary diseases can be better identified and treated using this technique.

Answer 1

Proton mri imaging helps in assessment of lung function and structure without hyper polarisation that is an absolute requirement for multinuclear acquisition.

This can detect lung tumours, pleural disorders, lymphadenopathy, blood vesselmproblems, v/q mismatch.

advantage -proton mri is free of any kind of harmful radiation as it dies imaging, by creating a magnetic field, thus repeated measurement of lungs does not cause any kind of harm, it is helpful in measuring various lung volume, and conditions of blood vessel so helpful in giving an idea about ventilation and perfusion of lung.

Disadvantage- there are contraindications like metallic implants, cardiac pacemaker.

High cost, so non accessible to a majority of population.

Proton MRI is an advanced modality in early diagnosis of various lung disease. MRI provide better tissue characterisation helpingbin diagnosing disease like interstitial lung disease. it can overcome the drawbacks of xray and ct and it is helpful by giving simultaneous functional and structural information.
