Abdominal CT
4
Feb

Overview

Abdominal CT provides detailed evaluation of organs and vasculature. It is used for trauma infection and oncologic staging. Contrast enhancement improves lesion detection.

Liver Imaging

CT characterizes liver lesions and assesses vascular anatomy. Multiphasic protocols improve detection of hepatocellular carcinoma. CT complements ultrasound and MRI in liver evaluation.

Bowel Imaging

CT enterography evaluates inflammatory bowel disease and small bowel tumors. It provides luminal and extraluminal assessment. Oral and IV contrast protocols optimize visualization.

Renal and Adrenal

CT assesses renal masses stones and adrenal lesions. It guides interventional procedures and surgical planning. Functional assessment may require additional imaging.

Imaging for Endocrine Disorders
4
Feb

Overview

Imaging localizes endocrine tumors and assesses gland structure and function. Modalities include ultrasound CT MRI and nuclear medicine. Imaging guides surgical planning and medical management.

Thyroid Imaging

Ultrasound characterizes nodules and guides fine needle aspiration. Nuclear medicine thyroid scans assess function and guide therapy in hyperthyroidism. Risk stratification informs management decisions.

Adrenal and Pituitary

CT and MRI evaluate adrenal masses and pituitary lesions with high resolution. Functional imaging and biochemical correlation determine clinical significance. Imaging supports endocrine and surgical planning.

Nuclear Techniques

SPECT and PET tracers localize neuroendocrine and metastatic disease. Theranostic approaches combine imaging and targeted therapy in select tumors. Multidisciplinary care integrates imaging with endocrine evaluation.

Endocrine System

Feb

Overview

The endocrine system regulates metabolism growth reproduction and homeostasis via hormones secreted by glands. Major glands include the pituitary thyroid parathyroid adrenals pancreas and gonads. Hormonal feedback loops maintain physiologic balance.

Pituitary and Hypothalamus

The hypothalamus controls pituitary hormone release via releasing and inhibiting factors. The pituitary secretes trophic hormones that regulate peripheral endocrine glands. Pituitary dysfunction affects multiple downstream systems.

Thyroid Parathyroid and Adrenals

The thyroid regulates metabolic rate and calcium homeostasis via thyroid hormones and parathyroid hormone. Adrenal glands produce cortisol aldosterone and catecholamines for stress response and electrolyte balance. Imaging and biochemical tests evaluate glandular disorders.

Clinical Relevance

Endocrine disorders include hypothyroidism hyperthyroidism adrenal insufficiency and pituitary tumors. Imaging such as ultrasound CT and MRI localize lesions and guide therapy. Hormone assays complement imaging for diagnosis and monitoring.
