OR

 

The patient had a CT scan of the abdomen and pelvis that, by report, showed appendicitis and inflammation.

 

I know which one I would choose, but I do not have justification or an explanation, and I need to.

The parenthetical phrase, 'by report', should be separated from the rest of the sentence. Next is the use of 'which' vs. 'that'. Normally, 'that' is used with a restrictive clause, or a clause that is essential to the meaning of the sentence, and 'which' is used with a non-restrictive clause. Non-restrictive clauses also need to be separated by commas.

 

Is '...showed appendicitis and inflammation.' restrictive or non-restrictive. I say that it is non-restrictive because it isn't essential to the meaning of the sentence. If it were, left out, the sentence would still make sense. The patient had a CT scan of the abdomen and pelvis.

It seems to me that a combination of the two examples is what is correct. We need the comma after 'pelvis', we need 'which', and we need to separate the parenthetical phrase from the rest of the sentence.

 

Let's build the sentence step by step.

The patient had a CT scan of the abdomen and pelvis. - simple sentence

The patient had a CT scan of the abdomen and pelvis, which showed appendicitis and inflammation. - complex sentence with the addition of dependent, non-restrictive clause.

The patient had a CT scan of the abdomen and pelvis, which, by report, showed appendicitis and inflammation. - complex sentence with the addition of parenthetical expression.
