Spec. MD. Mehmet Celik

A 28-year-old female professional freediver from Antalya presented with recurrent episodes of transient neurological symptoms after deep dives. Dr. Celik performed a specialized contrast-enhanced MR angiography protocol he developed for diving medicine, identifying a previously undetected patent foramen ovale with right-to-left shunting only under simulated pressure conditions. His precise imaging allowed for targeted percutaneous closure, enabling her to return to competitive freediving within three months.

A 72-year-old retired calligrapher from Istanbul's historic district arrived with unexplained weight loss and abdominal discomfort. Multiple previous scans elsewhere were inconclusive. Dr. Celik utilized dual-energy CT with iodine mapping, revealing a subtle neuroendocrine tumor in the jejunum measuring only 8mm, a finding missed on conventional imaging. His detailed report guided successful laparoscopic resection, with the patient making full recovery and returning to his art.

A 7-year-old Syrian refugee child presented with developmental delay and recurrent infections. Dr. Celik identified Kartagener syndrome through high-resolution chest CT showing complete situs inversus and bronchiectasis, the first definitive diagnosis in the child's medical journey. He coordinated with pediatric pulmonology to establish a management plan, dramatically improving the child's quality of life through targeted therapies.

A 45-year-old long-haul truck driver from eastern Anatolia was referred after a roadside collapse. While initial brain CT was normal, Dr. Celik's suspicion led him to perform CT perfusion imaging, revealing watershed ischemia patterns suggesting giant cell arteritis. Temporal artery ultrasound confirmed the diagnosis, preventing potential blindness through immediate steroid therapy, a condition typically missed in his demographic.

A 70-year-old retired teacher presented with progressive hearing loss. Dr. Celik's innovative use of photon-counting CT (a new technology at Medical Park Goztepe) revealed cochlear otosclerosis with precise fenestral involvement, guiding successful stapedectomy that restored hearing to near-normal levels after decades of deterioration.
