For interpreting radiologists and clinicians, evaluation of an injured knee using MRI requires knowledge of the proper imaging techniques, normal and aberrant anatomy, and the clinical significance of detected abnormalities. A coronal, proton-density (PD) MRI scan of the medial collateral ligament (MCL) is seen below.rade II medial collateral ligament tear seen on a coronal proton density image shows slight thickening of the medial collateral ligament and separation from the underlying cortices (arrows).
Common symptoms of nasal polyps in dogs include noisy breathing, sneezing and reverse sneezing, nasal discharge, stuffy nose, sneezing and nose bleeds affecting only one nostril. Because nasal polyps provide bacteria with places to hide, itâs not unusual for affected dogs to develop secondary bacterial infections.
Nasal polyps (singular: nasal polyp) are fleshy swellings, or polypoidal masses that develop in the lining of the nose and paranasal sinuses (air-filled spaces, communicating with the nasal cavity, within the bones of the skull and face).olyps in just one side of the nose are not common. Large polyps and/or clusters can cause breathing difficulties. They can affect the patient's sense of smell. They may block the sinuses and cause frequent infections and other problems.
