Positron Emission Tomography01:29

Positron Emission Tomography

6.2K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

The Parathyroid Glands00:59

The Parathyroid Glands

5.2K
The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

732
Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Imaging Studies for Cardiovascular System V: CT

673
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

    Area of Science:

    • Endocrinology
    • Radiology
    • Surgical Oncology

    Background:

    • Recent advancements in diagnostic imaging have improved the detection of parathyroid abnormalities.
    • Techniques like computed tomography, ultrasonography, and scintigraphy are now more refined.

    • Discussion of invasive methods like venous sampling and selective angiography.
    • Analysis of the current role of imaging in the pre-surgical evaluation of primary hyperparathyroidism.

    Main Results:

    • Imaging techniques have enhanced the identification of focal and diffuse parathyroid abnormalities.
    • Invasive methods are less utilized due to the need for specialized personnel.
    • The routine use of pre-operative imaging for all primary hyperparathyroidism cases is debated due to high surgical cure rates.

    Conclusions:

    • Diagnostic imaging is valuable for patients with persistent or undetected parathyroid abnormalities after initial surgery.
    • Further prospective studies are necessary to establish the cost-effectiveness of routine pre-surgical localization.
