Thoracic Imaging CT and MRI for Lung Disease
26
Feb

Introduction

CT is the cornerstone for evaluating interstitial lung disease pulmonary nodules and thoracic malignancy while MRI provides complementary soft tissue and vascular assessment. High resolution CT protocols and standardized reporting improve diagnostic accuracy. Multimodality imaging supports staging and treatment planning.

Interstitial Lung Disease

High resolution CT with thin slices and inspiratory expiratory phases characterizes patterns of fibrosis and guides multidisciplinary diagnosis. Quantitative CT metrics and serial imaging monitor progression and response to therapy. Correlation with pulmonary function tests and clinical history is essential.

Nodule Evaluation and Oncology

Low dose CT screening detects pulmonary nodules and follow up protocols use size and growth criteria to guide management. PET CT provides metabolic assessment for staging and characterization of indeterminate nodules. MRI is useful for chest wall mediastinal and cardiac invasion assessment in thoracic oncology.

Reporting and Multidisciplinary Care

Standardized reporting systems and multidisciplinary thoracic oncology boards improve staging and treatment decisions. Imaging guides biopsy planning surgical resection and radiation therapy. Close collaboration with pulmonology and oncology ensures integrated care.

Thoracic Imaging

Overview

Thoracic imaging includes radiography CT and PET for lung and mediastinal disease. It evaluates infection neoplasm and interstitial lung disease. Imaging guides biopsy and surgical planning.

Lung Nodule Evaluation

CT characterizes lung nodules and assesses growth over time. Low dose CT is used for lung cancer screening in high risk patients. PET CT helps determine metabolic activity of nodules.

Cardiothoracic Applications

CT angiography evaluates pulmonary embolism and vascular anomalies. Cardiac CT assesses coronary disease and structural abnormalities. Imaging supports interventional and surgical decision making.

Interstitial Lung Disease

High resolution CT characterizes interstitial lung disease patterns. Imaging helps differentiate causes and guide management. Serial imaging monitors disease progression and response.

Thyroid and Parathyroid

Feb

Overview

The thyroid gland produces hormones that regulate metabolic rate while parathyroid glands control calcium homeostasis via parathyroid hormone. Thyroid follicles synthesize thyroxine and triiodothyronine and parathyroids respond to serum calcium levels. Gland dysfunction affects multiple organ systems.

Thyroid Structure and Function

Thyroid follicles concentrate iodine and produce thyroid hormones that influence metabolism growth and thermogenesis. Nodules goiters and autoimmune thyroiditis alter function and structure. Ultrasound and nuclear imaging evaluate nodules and function.

Parathyroid Physiology

Parathyroid glands secrete PTH to increase serum calcium by acting on bone kidney and intestine. Hyperparathyroidism causes hypercalcemia and bone loss while hypoparathyroidism leads to hypocalcemia. Localization imaging guides surgical removal of adenomas.

Clinical Relevance

Thyroid and parathyroid disorders include hypothyroidism hyperthyroidism nodules and hyperparathyroidism. Imaging and biochemical testing guide diagnosis and surgical planning. Endocrine therapy and surgery address functional and structural disease.
