What is the difference between CT scan and MRI scan?

Question

Hello doctor,

Two weeks ago, a computed tomography (CT) scan showed a single 0.39 inches of small isodense nodular lesion in the liver. The follow-up computed tomography scan which was taken one week later, and the ultrasound was clear. Computed tomography scan was done in different hospitals, so there cannot be any comparison. Do I need further evaluation like Magnetic resonance imaging (MRI) or comparison of computed tomography?

Please help me.

Thank you.

Hi,

Welcome to icliniq.com.

I can understand your health concerns and am ready to help you with this.

Radiology is always an operator-dependent modality. It totally depends upon the person reporting, and how experienced and expert he is. It is very common to have over-reported computed tomography scans. In this scenario, we already go back to radiology and discuss computed tomography scan images with them or ask another consultant to give an opinion on an already done computed tomography scan. In your case, the best way forward would be to take images of both computed tomography scans and discuss or re-report by one of the experienced third radiologists. He should be doing an independent analysis, without seeing prior reports of computed tomography scans. Ultrasound is not very effective in detecting small lesions, a computed tomography scan is the investigation of choice. If still there is doubts, you might need a magnetic resonance imaging (MRI) liver with contrast to evaluate this 0.39 inches nodule.

Wishing you good health.

I hope your query got resolved.
