Let me share with you some limitations of the radiology reports:
Diagnosis vs anatomical specificity
The radiologist’s role is to examine the brain scans and suggest the most likely diagnosis. To achieve this, they examine the pathological processes they see in brain images. The exact location and extent of the lesion is of secondary importance to the radiologist.
We, as rehabilitation clinicians, usually know the diagnosis of our clients. What we want to know, is how the diagnosis affects our client’s function. For this kind of insight, we need to know the exact location and extent of the lesion because it directly impacts their function.
If you examine the radiology reports carefully you will find that they rarely provide us with the anatomical specificity we need. For example, a radiology report may describe a lesion in the “MCA territory”. However, “MCA territory” doesn’t specify which parts of the lobes are affected, and sometimes not even whether the lesion is in the frontal / parietal or temporal lobes. This is important information because variations in anatomical loci of strokes, are one of the main reasons for the wide range of clinical presentations.

Lesion location – description vs picture
You know the saying “A picture is worth 1000 words”?
Well, it applies to brain images too. It is challenging to describe the exact location of a lesion using words (in the radiology report). It is much easier to appreciate the specific location and extent of the lesion if you look at the brain images themselves.
When you look at the images you can appreciate how far the lesion extends (superiorly – inferiorly, anteriorly – posteriorly and medially – laterally), and just as importantly, which anatomical structures are spared. This level of detail is missing from the radiology reports.
Radiology language and focus
Often rehabilitation clinicians don’t fully understand the radiology reports, because radiologists use their own vocabulary. We were not necessarily taught this vocabulary; therefore, we need to learn it to fully understand the radiology reports.
Furthermore, since radiologists are interested in the diagnosis, the reports focus on the pathological processes and differential diagnoses. This gives the neurologists direction for further tests, examinations and most importantly treatment options. However, this discussion may not be relevant to us, if we already know the diagnosis of our client.
In summary, we as rehabilitation clinicians need to look at the brain images, because we need to be clear about the exact location and extent of the lesions. Relying on the radiology reports is insufficient, because the reports may not have the degree of details we require.
