Advances in imaging of lymph flow disorders

Area of Science:

• Diagnostic imaging
• Lymphatic system research
• Vascular medicine

Background:

• Conventional oil-contrast lymphography is largely replaced by advanced imaging techniques.
• Computed tomography (CT) and magnetic resonance (MR) imaging have impacted lymphatic diagnostics.
• Lymphangioscintigraphy has been refined for high-resolution peripheral lymphatic imaging.

Purpose of the Study:

• To highlight the diagnostic and therapeutic applications of lymphangioscintigraphy.
• To detail the role of advanced imaging in lymphatic circulatory disorders.
• To guide the diagnostic workup for peripheral lymphatic dysfunction.

Main Methods:

• Lymphangioscintigraphy for high-resolution imaging of lymphatic vessels and lymph flow.
• MR imaging for complex lymphatic disorders and treatment monitoring.
• CT imaging for guiding interventional procedures like sclerosis or obliteration.
• Ultrasonography for filariasis-related lymphatic issues.

Main Results:

• Lymphangioscintigraphy provides crucial insights into lymph flow dynamics and lymphatic anatomy.
• It is indispensable for diagnosing and understanding the evolution of lymphedema.
• The procedure is noninvasive, repeatable, and safe for lymphatic endothelium.
• MR and CT imaging complement lymphangioscintigraphy in managing complex cases and guiding interventions.

Conclusions:

• Lymphangioscintigraphy is vital for diagnosing lymphatic circulatory disorders and lymphedema.
• It aids in evaluating treatment efficacy for lymphatic flow.
• Patients with suspected lymphatic dysfunction should undergo lymphangioscintigraphy, potentially with MR imaging, for accurate diagnosis and therapy guidance.
