• A patient presents with sudden onset of blurring vision, micropsia and central scotoma. Fundus examination shows an oval area of retinal elevation in the macula and fundus angiography shows a smokestack configuration of fluorescein dye leaking from the choriocapillaris. He is most likely suffering from Central Serous Chorioretinopathy.
• Fluorescein angiography done in a case of Cystoid Maculae Edema shows leakage of fluorescein dye from the perifoveal retinal capillaries and peripapillary region, and accumulating in a flower-petal pattern around the fovea.
• Best test to determine etiology of SAH is inter-arterial digital Substraction Angiography.
• In patient with high clinical suspicion of pulmonary thromboembolism, best investigation would be CT Angiography.
• Lens and cornea are avascular structures of eye that’s why fluorescein angiography can’t be used to identify lesions.
• Dye is injected in carotid artery in cerebral angiography.
• The initial investigation of choice for a post cholecystectomy biliary stricture is Magnetic Resonance Cholangiography.
• The gold standard for the definitive diagnosis of the extrahepatic biliary atresia is Peroperative Cholangiography.
• In cholangiography CBD stone appears as Meniscus Sign.
• Cholangiography via T-tube done after 10-14 days of cholecystectomy.
• Dye used in IV cholangiography is Biligraffin.
• Lymphangiograpgy of the leg is performed by Dissecting lymphatics through an incision on the dorsum of the foot .
• Premature filling of veins is a manifestation in cerebral angiography of Arteriovenous Malformation.
• The glomus tumor invasion of jugular bulb is diagnosed by Jugular Venograpgy.
• Magnetic Resonance Angiography is the most specific screening test for renovascular hypertension.
• Contrast Enhanced Arteriography (Angiography) is the most definitive diagnostic procedure for the diagnosis of Renal Artery stenosis while Magnetic Resonance Angiography (MRA) is the most sensitive and specific non invasive test (screening test) for its diagnosis.
• Cerebral angiography was performed by Egas Moniz.
• Angiography is the investigation of choice in Central Serous Retinopathy.
• A young adult presents with proptosis and pain in eye after 4 days of trauma to eye. Chemosis, conjunctival congestion and extraocular muscle palsy with inability to move eye are seen. Investigation of choice is Digital Substraction Angiography.
• Transfemoral route is the preferred route for cerebral angiography.
• Investigation of choice for diagnosing lung sequestration is Angiography.
• Vessels catheterized on carotid angiography are 2 internal carotids and  1 vertebral.
• CT scan shows a suharachnoid haemorrhage following symptoms of sudden headache and paralysis. Next investigation of choice is: 4 vessel Angiography.
• Coronary CT angiography is best for Coronary Plaque lesions.
• Puff of smoke appearance on cerebral angiography is seen in Moyamoya disease.
•  Fluorescein angiography is used in 😕
  • Diabetic retinopathy
  • Neoplasm
  • Papilloedema
  • Central serous retinopathy
  • Retinitis pigmentosa and other retinal degeneration
  • Choroidal diseases : Choroidal neovascularization
  • Vascular occlusions (CRVO, CRAO)
  • Eale’s disease
  • Cystoid macular edema.
• Deep vein thrombosis post-operatively is diagnosed by Ascending venography.
