Takayasu arteritis diagnosed by 16-row multidetector CT angiography

Area of Science:

• Vascular Medicine
• Radiology
• Immunology

Background:

• Takayasu arteritis is a rare, chronic inflammatory condition affecting large arteries, primarily the aorta and its branches.
• Diagnosis traditionally relies on invasive catheter angiography, clinical symptoms, and laboratory markers.
• There is a need for non-invasive imaging modalities to assess arterial involvement and inflammation.

Purpose of the Study:

• To evaluate the utility of multislice computed tomography angiography (MSCTA) in diagnosing Takayasu arteritis.
• To demonstrate the non-invasive assessment capabilities of MSCTA for large vessel vasculitis.
• To present case studies illustrating MSCTA findings in Takayasu arteritis.

Main Methods:

• Utilized 16-slice multislice computed tomography angiography (MSCTA) for imaging.
• Acquired both angiographic and morphological data of the aorta, its branches, and pulmonary arteries.
• Correlated imaging findings with clinical presentation and laboratory results in two patients.

Main Results:

• MSCTA provided detailed, non-invasive angiographic visualization of affected arteries.
• The technique allowed for simultaneous assessment of arterial lumen and vessel wall morphology.
• Diagnostic findings consistent with Takayasu arteritis were confirmed in both presented cases.

Conclusions:

• Multislice computed tomography angiography (MSCTA) is a valuable non-invasive tool for diagnosing Takayasu arteritis.
• MSCTA enables comprehensive evaluation of luminal stenosis and mural inflammation in affected vessels.
• This imaging modality can supplement or potentially replace conventional angiography in select cases.
