Prof. M.D. Düzgün Yıldırım

A 28-year-old competitive freediver from Antalya presented with recurrent episodes of confusion after deep dives. Dr. Yıldırım performed a specialized cerebral perfusion MRI with hyperoxic and hypercapnic challenges, revealing a previously undocumented pattern of vascular shunting in the Circle of Willis that only manifested under simulated dive conditions. This discovery led to a new safety protocol for the athlete's training regimen, preventing potential neurological injury.

A 72-year-old retired calligraphy master with Parkinson's disease was referred for a tremor assessment. Instead of standard imaging, Dr. Yıldırım developed a real-time MRI protocol where the patient performed delicate brush strokes inside the scanner. The imaging captured unique cerebellar activation patterns correlating with artistic suppression of tremor—findings that contributed to a non-invasive neuromodulation therapy study.

A 7-year-old refugee child from Syria with unexplained recurrent fevers and abdominal pain had undergone multiple inconclusive tests. Dr. Yldırım utilized low-dose pediatric PET/MRI fusion imaging, identifying a tiny, migrating intraperitoneal wooden splinter from a playground injury years prior that conventional imaging had missed. The minimally invasive removal resulted in immediate symptom resolution.

A 41-year-old molecular gastronomy chef presented with sudden loss of taste discrimination. Dr. Yıldırım designed a functional MRI protocol incorporating olfactory and gustatory stimulation with molecular food compounds, mapping precise insular cortex abnormalities. The images revealed a rare vascular compression that was surgically corrected, restoring his professional capabilities within months.
