Diagnostic performance of hippocampal volumetry in Alzheimer’s disease or mild cognitive impairment: a meta-analysis [PDF]
European Radiology, 2022 Objective: To evaluate the diagnostic performance of hippocampal volumetry for Alzheimer's disease (AD) or mild cognitive impairment (MCI). Methods: The MEDLINE and Embase databases were searched for articles that evaluated the diagnostic performance of

Thermochimica Acta, 2022
In the commonly used technique of scanning calorimetry, one measures the heat capacity, , as a function of temperature on heating or cooling a material at a fixed rate. In the study of liquid-glass-liquid transition, a calorimetry scan is modelled in terms of a non-exponential parameter, , and non-linearity parameter, , which describe the shape of the -

Ultrasound volumetry in hematometrocolpos
Journal of Clinical Ultrasound, 1989AbstractSonographic measurements of the volume of blood collecting in hematometrocolpos has been carried out in 6 cases of imperforate hymen. Sonometry gave estimates of the amount of retained blood, which were 4% to 28% more than that actually evacuated. The vaginal collection was 5 times or more than the uterine collection.

CT volumetry of the skeletal tissues
Medical Physics, 2006Computed tomography (CT) is an important and widely used modality in the diagnosis and treatment of various cancers. In the field of molecular radiotherapy, the use of spongiosa volume (combined tissues of the bone marrow and bone trabeculae) has been suggested as a means to improve the patient‐specificity of bone marrow dose estimates. The noninvasive

Volumetry of the human amygdala — An anatomical study
Psychiatry Research: Neuroimaging, 2010A striking feature of the studies that have addressed the measurement of the amygdala is the wide range of volumes encountered, with reports of volumes ranging from 1 to almost 4 cm(3). Another striking feature is the number of discrepancies in the landmarks adopted for manual tracing in magnetic resonance imaging (MRI).

Stereological MRI volumetry of the frontal lobe
Psychiatry Research: Neuroimaging, 1996Stereology was used to measure frontal lobe volume on magnetic resonance imaging (MRI) scans in a multi-observer repeated-measures trial in 17 adults. Prior to measurement, MR image volumes were reoriented into coronal sections perpendicular to the bicommissural plane. Three observers blinded to subject identify repeatedly used fixed grid stereology to

Cerebral Ventricular Volumetry in Pediatric Neuroimaging
2002A prospective NIH funded study examines the effects of early brain damage on selective aspects of cognitive development in children. We describe an efficient method to segment and visualize the intracerebral fluid spaces in children and adults based on MRI and to quantify ventricular volumes which is (a) robust (for normal and pathological anatomy), (b)

[Sonographic volumetry of the thyroid].
Aktuelle Radiologie, 1993The utility of ultrasound volumetry of the thyroid is discussed on the basis of 414 different examinations. Analysis of the possible errors in calculations and the importance of the experience as well as practice are emphasized. According to the results of the cadaver studies, the difference between the in situ size and the size of the removed thyroid ...

Assessment of a procedure for left ventricle volumetry
Physics in Medicine and Biology, 1987A three-step radiographic procedure is described for the determination of left ventricle volumes, based on one lateral and two angled single plane images. The first angled image is taken to yield a minimally foreshortened LV image and the second image, at the same angle, is taken of a calibration sphere.
