Below are two organizations that will read MRI & CT scans (with or without contrast) and give a second opinion if you believe you haven’t received an accurate assessment from your initial radiology report. They do charge a significant fee for doing this. I checked with MD View, & their fee starts at $650. I don’t know what Radiology Business charges.
And another posted by @boogs99:
I recall seeing a post from someone else who paid for a second opinion & provided a link, but I don’t recall who it was. I’ll add the link here when I find it.
