Heart wall is thicker on postmortem computed tomography than on antemortem [corrected] computed tomography: the first...

Area of Science:

• Radiology
• Forensic Pathology
• Medical Imaging

Background:

• Accurate assessment of cardiac morphology is crucial in both clinical and forensic settings.
• Understanding postmortem changes in imaging is essential for reliable interpretation.

Purpose of the Study:

• To compare heart wall thickness on postmortem computed tomography (PMCT) with ante mortem CT (AMCT) in the same patients.
• To validate PMCT findings against pathological autopsy results.

Main Methods:

• A study of 57 patients who underwent AMCT, PMCT, and autopsy.
• Cardiac chambers were measured at five sites by radiologists.
• Statistical analysis compared AMCT, PMCT, and pathological measurements.

Main Results:

• Heart walls were significantly thicker on PMCT than AMCT (p < 0.0001).
• PMCT measurements were thicker than pathological specimens using standard mensuration.
• No significant difference was found when including papillary muscles and epicardial fat.

Conclusions:

• This study confirms increased heart wall thickness on PMCT compared to AMCT in the same patients.
• Postmortem CT findings for heart wall thickness are supported by pathological evidence.
