Transcranial Doppler is a diagnostic procedure used to measure the velocity and direction of blood from the arteries by measuring reflection created from ultrasound waves which are moving transcranially (through the cranium).A low-recurrence transducer of less than 2 MHz is utilized to power adequate transmission of ultrasound waves through the cranium of the brain. Such ultrasound examination is carried out to monitor the blood flow in the brain. Transcranial Doppler ultrasound technique is safe, noninvasive and free from ionizing radiation. Transcranial Doppler ultrasound can be used alone or with other diagnostic examinations such as MRI, MRA and CT scans. The diagnostic is also effective in detecting sickle cell disease, ischemic cerebrovascular disease, subarachnoid hemorrhage, arteriovenous malformations, and cerebral circulatory arrest.
Based on equipment type, The Transcranial Doppler Market can be divided into imaging and nonimaging device. The imaging device segment is projected to grow at a significant rate due to addition of more efficient features called power motion mode which provides multi-gate flow information such as blood flow signal.In terms of application, the market can be categorized as sickle cell disease, acute ischemic stroke, intracranial steno occlusive disease, and microemboli detection. However, application of transcranial Doppler in sickle cell disease is increasing as the disease has high risk of stroke in the early years of childhood and prevention of first stroke was made possible through the use of transcranial Doppler ultrasound.
Moreover, currently transcranial Doppler is one of the recommended method for prevention of primary-stroke. Technological advancement in brain monitoring devices, rising incidence of mental disorders, portability, and product repeatability are considered as the major drivers of the transcranial Doppler market. In addition to these factors, worthy investments made in the healthcare sector by government and private players, along with the increasing number of mergers, acquisitions, and partnerships between the leading companies in this market, is also responsible for its progressive growth. Unfavorable reimbursement policies, shortage of skilled technical operator, inability to measure large basal arteries are some factors that hamper market growth.
