The Parathyroid Glands00:59

The Parathyroid Glands

5.4K
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...

Imaging Studies III: Computed Tomography

425
DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

495
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

400
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...

Imaging Studies V: Intravenous Urography and Retrograde Pyelography

1.8K
IntroductionIntravenous Urography (IVU) and Retrograde Pyelography (RP) are important diagnostic imaging techniques used to evaluate the urinary system. These methods help identify structural abnormalities, obstructions, and functional issues in the kidneys, ureters, and bladder. Both procedures use iodine-based contrast media to enhance the visibility of urinary tract structures on X-ray images, though they differ in their methods and indications.1. Intravenous Urography (IVU)Intravenous...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

545
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Area of Science:

  • Endocrinology
  • Medical Imaging
  • Surgical Anatomy

Background:

  • Primary hyperparathyroidism (PHPT) involves overactive parathyroid glands producing excess parathyroid hormone (PTH).
  • Minimally invasive surgery for PHPT necessitates accurate pre-operative localization of abnormal parathyroid glands.
  • Current imaging modalities for PHPT localization vary in efficacy, with no single method being universally superior.

Purpose of the Study:

  • To review the background and anatomy relevant to primary hyperparathyroidism.
  • To discuss established and emerging imaging modalities for parathyroid localization.
  • To provide updates on the utility of various imaging techniques in PHPT.

Main Methods:

  • Review of existing literature on parathyroid imaging techniques.
  • Discussion of nuclear medicine scintigraphy and ultrasound imaging.
  • Exploration of multiphase or 4-dimensional computed tomography (4D-CT) as an emerging modality.

Main Results:

  • Established modalities like scintigraphy and ultrasound are widely used for parathyroid localization.
  • Multiphase or 4D-CT presents emerging advantages for imaging parathyroid lesions.
  • The choice of imaging modality depends on various factors, and no single method is definitively superior.

Conclusions:

  • Accurate parathyroid imaging is crucial for successful minimally invasive surgery in PHPT.
  • Nuclear medicine, ultrasound, and 4D-CT are key modalities for parathyroid localization.
  • Ongoing advancements in imaging technology continue to improve PHPT diagnosis and surgical planning.
