Imaging of autoimmune diseases

Area of Science:

• Medical Imaging
• Immunology
• Radiopharmaceuticals

Background:

• Autoimmune diseases are diverse, presenting with varied immunological changes and clinical symptoms.
• Diagnosis often occurs at symptom onset, impacting treatment and prognosis.
• Effective imaging is crucial for assessing disease extent, severity, and treatment response.

Purpose of the Study:

• To review diagnostic imaging approaches for autoimmune diseases.
• To highlight the role of nuclear medicine and novel radiopharmaceuticals.
• To guide the selection of appropriate diagnostic methods based on disease criteria.

Main Methods:

• Conventional imaging: Ultrasound (US), conventional radiology, computed tomography (CT) for morphological assessment.
• Advanced imaging: Magnetic Resonance Imaging (MRI) for biochemical and structural changes.
• Nuclear medicine: Techniques utilizing radiolabeled receptor ligands for sensitive and specific detection.

Main Results:

• New radiopharmaceuticals enable non-invasive in vivo detection of tissue changes via specific receptor binding.
• Nuclear medicine offers high sensitivity and specificity in evaluating autoimmune conditions.
• The review discusses criteria for choosing diagnostic approaches across various autoimmune diseases.

Conclusions:

• Nuclear medicine, particularly with novel radiopharmaceuticals, plays a significant role in autoimmune disease diagnosis and management.
• Accurate imaging aids in disease prevention, risk identification, and preclinical diagnosis.
• Tailored imaging strategies are essential for optimizing patient care in autoimmune pathologies.
