Sinus clinics are increasingly choosing CT scans for diagnostic imaging for the technology's numerous advantages over traditional X-rays.

CT (computed tomography) scanning technology has been proven to be cheaper, more convenient and more accurate than X-rays for diagnosing sinus problems, including chronic sinusitis.

“CT scans allow us to identify structural issues that may correlate with symptoms,” Diana Ruiloba, a physician assistant at Arizona Breathe Free Sinus & Allergy Centers, told the Arizona Business Daily. “It allows us to identify evidence of chronic sinusitis. Having a CT scan during the first visit allows for a medical plan to be set in place without waiting for imaging results to verify the  diagnoses. We are able to review the full CT scan with patients during their initial visit, essentially creating a concierge concept in medical care."

Sinus problems such as chronic sinusitis can lead to headaches, congestion, facial pain, earaches and other symptoms.

"Chronic sinusitis can have many significant consequences to one’s health," said Dr. John Stewart of Arizona Breathe Free. "If left untreated, it can affect not only one’s nasal passageways and respiratory system, but your cardiovascular health as well. Chronic sinusitis can lead to nasal obstruction, which, if untreated, can cause sleep apnea. Subsequently, if sleep apnea is left untreated, it can negatively impact the heart, causing heart arrhythmias (such as atrial fibrillation), stroke."

A study published in the Academy of Emergency Medicine found that traditional sinus X-rays may not be as reliable as sinus CT scans for diagnosing acute sinusitis

"Sinus X-rays are less sensitive than sinus CT scans for demonstration of radiographic changes consistent with acute sinusitis," the study concluded. "Sinus plain films may not be reliable enough to assist with clinical decision making. If severity of patient illness requires diagnostic certainty, more sensitive imaging studies, such as CT scans of the sinuses, should be considered."

Doctors at the University of Kansas School of Medicine reported that regular X-rays have a limited role in the management of sinusitis and that noncontract CT images can define the nasal anatomy much more precisely. 

Sinusitis accounts for approximately 25 million doctor visits every year, costing more than $2 billion annually in direct medical expenses, according to Vital Health Statistics reports.
