A lucency just means a dark area on the x-ray/CT as opposed to an opacity (which is a white area). I'm not sure what type of CT scan you got (i.e. with or without contrast injection), but don't jump to conclusions about it being cancer..... lucency just means a dark area on the x-ray/CT as opposed to an opacity (which is a white area).

The operational details of amplifiers are buried in the field of electronics, but for audio purposes it is usually safe to say that current commercial audio amplifiers are so good that a normally operating amplifier is seldom the limitation on the fidelity of a sound reproduction system.
Inside the scanner are coils of metallic wire. When electricity passes through the coils, a magnetic field is created and the coils vibrate. The sound the MRI makes is the metal coils vibrating and banging together inside the machine, creating a very strong magnetic field.The sound may reach up to 100 Decibels, so patients are required to use ear protection. We also have a sound system so the patient may enjoy music through headphones while being scanned.he sound the MRI makes is the metal coils vibrating and banging together inside the machine, creating a very strong magnetic field.
