Abstract:
Clinicians working with oropharyngeal swallowing disorders often use videofluoroscopy to define their patients' swallowing abnormalities. This study examined the effect of 4 hours of training in the identification of head and neck anatomy and oropharyngeal swallowing disorders viewed radiographically. Ninety clinicians participated in a 5-hour session which included 30-minute pre- and post-tests requiring identification of head and neck anatomy and oropharyngeal swallowing disorders and a 4-hour training period. Results showed significant improvement in identification of both radiographic anatomy and swallowing disorders. The change in pre- and post-test measures was negatively correlated with extent of prior experience in dysphagia. Similar studies are needed with clinicians or students inexperienced in dysphagia to define the number of hours of education needed in order for students to reach a desired accuracy level in their identifications.

Radiological Investigation I: X-ray and CT
Radiological Investigation II: MRI and Ventilation Perfusion Scan
Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
