M.D. Gökay Karaça

A 28-year-old competitive freediver from the Aegean coast presented with unexplained episodes of transient visual disturbances during deep dives. Dr. Karaça employed a specialized low-field MRI protocol to simulate pressure changes, revealing a previously undiagnosed micro-arteriovenous malformation in her occipital lobe that only became symptomatic under extreme pressure. The minimally invasive embolization he guided through interventional radiology allowed her to return to competition within three months.

A 72-year-old retired olive grove owner with limited financial means and no prior imaging history arrived with worsening back pain. Conventional scans were inconclusive, but Dr. Karaça personally performed a contrast-enhanced ultrasound, identifying a rare psoriatic arthritis mimic affecting the sacroiliac joints. He connected the patient with a hospital assistance program for biologic therapy, leading to significant pain relief without financial ruin.

An 8-year-old boy, an immigrant from Syria with a complex war injury history, had a persistent cough. His family was deeply distrustful of medical systems. Dr. Karaça used a low-dose pediatric CT protocol and discovered a retained, migrating shrapnel fragment near his bronchus. By involving a cultural mediator and using 3D-printed models to explain the procedure, he gained the family's trust for a successful CT-guided retrieval.

A 45-year-old high-stress finance executive presented for a routine coronary calcium scan. Dr. Karaça noticed an incidental, atypical pattern of microcalcifications in the left breast, not on the standard radiology report template. He insisted on a dedicated mammogram and ultrasound, diagnosing an early-stage, non-palpable DCIS. The patient's intense work schedule delayed treatment for a month, but she achieved full recovery after lumpectomy.
