Postmortem magnetic resonance imaging: Reproducing typical autopsy heart measurements

Legal Medicine, 2015
The aim of this study was to evaluate the utility of cardiac postmortem magnetic resonance (PMMR) to perform routine measurements of the ventricular wall thicknesses and the heart valves and to assess if imaging measurements are consistent with traditional autopsy measurements.In this retrospective study, 25 cases with cardiac PMMR and subsequent ...

Cerebral Tuberous Sclerosis: Postmortem Magnetic Resonance Imaging and Pathologic Anatomy

Mayo Clinic Proceedings, 1989
We conducted postmortem magnetic resonance imaging (MRI) studies of five brains from patients with a clinical and pathologic diagnosis of tuberous sclerosis. Areas of prolonged T1 and T2 relaxation could easily be identified within the white matter subjacent to the cortical tubers despite formalin fixation and storage. The signal changes were identical

Fetal heart pathology on postmortem 3‐T magnetic resonance imaging

Prenatal Diagnosis, 2013
ABSTRACTIntroductionPostmortem magnetic resonance imaging (pmMRI) is increasingly used in perinatology, typically as an alternative or complement to conventional necropsy for central nervous system anomalies. Overall, it provides reliable information on structural malformations but was shown to be of limited use in examining the fetal heart.ObjectiveWe

Comparison of Postmortem Magnetic Resonance Imaging and Neuropathologic Findings in the Cerebral White Matter

Archives of Neurology, 1991
Two types of high-signal intensity abnormalities are frequently found bilaterally in the cerebral white matter of brains of elderly patients on T2-weighted magnetic resonance imaging (MRI) scans. One is located in the immediate periventricular region; the other, in the deep subcortical white matter (centrum semiovale).

Postmortem magnetic resonance images of the injured brain: Effective evidence in the courtroom

Forensic Science International, 1991
Magnetic resonance images (MRI) of the whole, formalin-fixed brain produce details of pathologic changes deep within brain substance not apparent on external examination. Photographs of these radiographic images present pathologic features in a black-and-white, 2-dimensional format which has proven particularly effective in court before judge and jury.

[Use of postmortem brain magnetic resonance imaging at autopsy].

Arkhiv patologii, 2008
The study was undertaken to define the possibilities of using postmortem MRI for examining the brain. A complex study was made to explore 21 neutral formalin-fixed gross brain specimens from patients with neurosurgical pathology. Macroscopic and target histological studies of the changed signal areas detected by MRI were performed using histochemical ...

Traumatic axonal injury revealed by postmortem magnetic resonance imaging: A case report

Legal Medicine, 2019
In forensic investigations, it is important to detect traumatic axonal injuries (TAIs) to reveal head trauma that might otherwise remain occult. These lesions are subtle and frequently ambiguous on macroscopic evaluations. We present a case of TAI revealed by pre-autopsy postmortem magnetic resonance imaging (PMMR).

Postmortem imaging of fetuses at early gestations: A comparison of microfocus computed tomography with postmortem magnetic resonance at 9.4 T and postmortem ultrasound

Prenatal Diagnosis
AbstractObjectiveTo compare the diagnostic performance of postmortem ultrasound (PMUS), 9.4 T magnetic resonance imaging (MRI) and microfocus computed tomography (micro‐CT) for the examination of early gestation fetuses.MethodEight unselected fetuses (10–15 weeks gestational age) underwent at least 2 of the 3 listed imaging examinations.

Value and Use of Pediatric Postmortem Magnetic Resonance Imaging.

Radiologic technology
The gold standard for postmortem investigations of fetal and pediatric deaths involving neurological pathologies is a traditional autopsy; however, acquiring all diagnostic information from an autopsy alone can be challenging. In addition, there are substantial obstacles to performing traditional autopsies on the pediatric population such as parental ...
