Interventsion radiologiya

Interventional radiology (IR) is a medical subspecialty that performs various minimally-invasive procedures using medical imaging guidance, such as x-ray fluoroscopy, computed tomography, magnetic resonance imaging, or ultrasound. IR performs both diagnostic and therapeutic procedures through very small incisions or body orifices. Diagnostic IR procedures are those intended to help make a diagnosis or guide further medical treatment, and include image-guided biopsy of a tumor or injection of an imaging contrast agent into a hollow structure, such as a blood vessel or a duct. By contrast, therapeutic IR procedures provide direct treatment—they include catheter-based medicine delivery, medical device placement (e.g., stents), and angioplasty of narrowed structures.

Interventsion radiologiya usullarining asosiy afzalliklari shundaki, ular tananing chuqur tuzilmalariga tana teshigi yoki kichik igna va simlar yordamida mayda kesma orqali etib borishi mumkin. Bu ochiq protseduralarga qaraganda xavflarni, og'riqni va tiklanishni kamaytiradi. Haqiqiy{0}}vaqtdagi vizualizatsiya, shuningdek, anormallikni aniq koʻrsatish imkonini beradi, bu esa protsedura yoki tashxisni yanada aniqroq qiladi. Ushbu imtiyozlar ichki tuzilmalarga zudlik bilan kirishning yo'qligi (qon ketish yoki teshilish sodir bo'lsa) va katarakt va saraton kabi radiatsiya ta'sirining qo'shimcha xavflari bilan taqqoslanadi.
