In 1945 Broch & Purcell described as Nuclear Magnetic Resonance. It was

used for chemical and biochemical analyses for long years. It was widely

used in medical applications after Lauterbur et al. ‘s study in 1973 (1).

The primary screening method for breast cancer is mammography as

known. It is the only method that positively affects survival. But its

sensitivity and specificity is not 100% and it can be an inadequate method

at some ages. Studies showed that: MRI imaging added mammography

increased success rates but increased false positivity rates can cause some

unnecessary invasive procedures. Although these breast MRI is widely used

for screening, diagnosis and staging (2).

More than 80 million MRI is worldwide applied yearly. Claustrophobia rates

are between 1-15% and more than 2 million breast MRI application is

interrupted for the necessitation of sedation (3). Melendez et al. noticed

that rate around 30%. Also 3-5% of these cases were interrupted due to

the sedation necessitation. Anxiety and claustrophobia can cause sequence

repeating, procedure cancellation and important time and labor loss.
