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 grow in inflamed tissue of the nasal mucosa. The mucosa is a very wet layer that helps protect the inside of your nose and sinuses and humidifies the air you breathe. During an infection or allergy-induced irritation, the nasal mucosa becomes swollen and red, and it may produce fluid that drips out.olyps can grow large enough to block your nasal passages, resulting in chronic congestion. Symptoms can include: 1  a sensation that your nose is blocked. 2  runny nose. 3  postnasal drip, which is when excess mucus runs down the back of your throat. 4  nasal stuffiness. 5  nasal congestion.
