Diagnostic Tests and Studies

An overview of the diagnostic tests used to evaluate conditions of the ear, nose, throat, thyroid, parathyroid, and related structures.

IMAGING STUDIES

Imaging tests create pictures of internal structures using different techniques, helping to characterize a growth, assess the extent of a condition, or guide further evaluation.

• CT

• MRI

• PET-CT

• SPECT-CT

• Ultrasound

• Radioiodine Uptake

BIOPSY AND PATHOLOGY TESTING

These tests examine cells or tissue samples, using a microscope or molecular techniques, to help determine whether a growth is benign or cancerous and to guide further classification.

• Needle Biopsy (FNA)

• Incisional Biopsy

• Punch Biopsy

• Pathology

• Molecular Testing (Thyroid FNA)

• Bethesda System

• TI-RADS

• HPV Liquid Biopsy and ctDNA

EAR FUNCTION TESTING

These tests measure hearing and how well the middle ear is functioning.

• Audiometry

• Tympanometry

THROAT AND SWALLOWING STUDIES

These studies evaluate the structures and function of the throat and esophagus, including how food and liquid move during swallowing.

• Fiberoptic Laryngoscopy

• Barium Swallow Study

• Modified Barium Swallow Study

• Swallow Evaluations

• Esophagogastroduodenoscopy (EGD)

• 24-hr pH and Impedance Probe

SLEEP AND BREATHING STUDIES

These studies assess breathing patterns during sleep and overall lung function.

• HSAT (Home Sleep Apnea Test)

• PSG (Polysomnogram)

• PFT

OTHER TESTS

Additional diagnostic tools address specific conditions.

• Allergy Testing

• Jugular Occlusion Test (Venous Hum)

The specific tests used in a given case depend on the condition being evaluated and the findings on clinical examination.
