Volume interrogation, or postprocessing of multidetector row computed tomography (MDCT) data, is crucial for pulmonary vascular analysis. Radiologists must master these problem-solving tools for accurate diagnosis of thromboembolic disease.

Area of Science:

Radiology
Medical Imaging
Cardiovascular Imaging

Background:

Multidetector row computed tomography (MDCT) has revolutionized medical imaging.
Traditional axial image review is becoming insufficient for complex datasets.

Purpose of the Study:

To define "volume interrogation" as the optimal postprocessing of MDCT data.
To highlight the role of interactive, near real-time analysis of isotropic datasets.
To review techniques for pulmonary vasculature assessment and their application in thromboembolic disease.

Main Methods:

Discussion of fundamental postprocessing tools for pulmonary vasculature analysis.
Illustration of clinical applications using MDCT data.
Focus on interactive, problem-solving approaches over preset protocols.

Main Results:

Volume interrogation is the preferred term for MDCT postprocessing.
Radiologist involvement and mastery of interactive tools are essential.
Reformatted images improve communication and diagnostic accuracy.

Conclusions:

Axial image review alone is suboptimal for MDCT interpretation.
Volume interrogation enhances the radiologist's role in clinical decision-making.
MDCT postprocessing is critical for diagnosing acute and chronic thromboembolic disease.
