Imaging Studies II: Positron Emission Tomography and Scintigraphy

358
Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

The Parathyroid Glands

4.0K
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

167
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

293
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...

Positron Emission Tomography01:29

Positron Emission Tomography

6.7K
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...

Imaging Studies for Cardiovascular System V: CT

165
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:

  • Primary hyperparathyroidism (PHPT) is a prevalent endocrine disorder.
  • Parathyroid adenoma is the most frequent cause of PHPT.
  • Surgical intervention is the primary curative treatment for PHPT.

Purpose of the Study:

  • To provide an overview of parathyroid imaging modalities for PHPT.
  • To discuss protocols, findings, and potential challenges in parathyroid localization.
  • To highlight key considerations for presurgical imaging in PHPT.

Main Methods:

  • Review of established and advanced parathyroid imaging techniques.
  • Discussion of ultrasound, sestamibi scanning, and 4DCT protocols.
  • Analysis of imaging findings, including pearls and pitfalls.

Main Results:

  • Ultrasound offers safe, rapid, radiation-free localization but is operator-dependent.
  • Sestamibi scans demonstrate sensitivity comparable to ultrasound, enhanced by tomographic imaging.
  • 4DCT serves as a valuable tool for complex cases and re-operations.

Conclusions:

  • Accurate presurgical localization of parathyroid adenomas is crucial for successful PHPT surgery.
  • A range of imaging modalities, each with specific advantages and limitations, are available.
  • Understanding imaging protocols and potential pitfalls optimizes patient management.
