Goiter01:27

Goiter

Goiter refers to an abnormal enlargement of the thyroid gland that may appear as a diffuse goiter (uniform enlargement) or nodular (single or multiple nodules). Functionally, it is classified as nontoxic (normal/low hormone levels) or toxic (excess hormone production).PathophysiologyDiffuse thyroid enlargement typically results from prolonged stimulation by thyroid-stimulating hormone (TSH) or TSH-like agents, commonly seen in hypothyroidism or iodine deficiency. In contrast, in hyperthyroid...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

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 III: Computed Tomography

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...

Imaging Studies II: Positron Emission Tomography and Scintigraphy

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.

Radiological Investigation I: X-ray and CT

Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and the...
Hyperthyroidism II: Pathophysiology01:27

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

Area of Science:

  • Endocrinology
  • Nuclear Medicine
  • Diagnostic Imaging

Background:

  • Multinodular goitre diagnosis relies on ultrasound, scintigraphy, and fine-needle biopsy.
  • Accurate preselection for treatments is vital, particularly in endemic goitre areas, to ensure efficacy and avoid unnecessary interventions.

Purpose of the Study:

  • To review diagnostic modalities for multinodular goitre.
  • To provide recommendations for nuclear medicine therapies, including radioiodine (I-131).

Main Methods:

  • Review of diagnostic techniques: ultrasound, scintigraphy, fine-needle biopsy.
  • Evaluation of indications for radioiodine (I-131) treatment.
  • Discussion of patient selection for surgical, medical, or radioiodine therapies.

Main Results:

  • Autoimmune hyperthyroidism (Graves' disease), solitary hyperfunctioning nodules, and toxic multinodular goitre (Plummer's disease) are indications for radioiodine treatment.
  • Radioiodine (I-131) shows emerging use for subclinical hyperthyroidism and non-toxic goitre to reduce thyroid volume when surgery is not feasible.

Conclusions:

  • Optimizing diagnostic work-up is key for effective multinodular goitre management.
  • Radioiodine (I-131) therapy offers valuable treatment options for various thyroid conditions, including non-toxic goitre and subclinical hyperthyroidism.
