The technology behind listening devices has improved dramatically in recent years, giving new hope to those with impairment. While still far from a perfect replacement for the natural ability to hear, these devices give those with a disabili If the vagina is not offering the firm grip to your male partner, he expresses displeasure in lovemaking.

Thismedical imaging technique is based on the principle of nuclear magneticresonance (NMR), a spectroscopic technique used by scientists to gathermicroscopic chemical and physical information about molecules. Magneticresonance imaging started out as a tomographic imaging technique, to produce animage of the NMR signal in a thin slice through the human body. Magneticresonance imaging uses a powerful magnetic field, radio frequency pulses and acomputer to produce detailed images of organs, soft tissues, bone and all otherinternal body structures of the body. Signs of arterial sclerosis in the heartcan be detected by this method. In the spine, bones, and joints it can findruptured disks, torn cartilage, and tumors.MRimaging of the body is performed to evaluate blood vessels, pelvic organsincluding the reproductive organs in the male (prostate and testicles) and thefemale (uterus, cervix and ovaries), breasts and organs of the chest andabdomen including the heart, liver, biliary tract, kidneys, spleen, pancreasand adrenal glands.During the examination, patientsmay require swallowing contrast material or they might receive an injection ofcontrast into the veins to enhance the appearance of blood vessels, tumors orinflammation. If the patient has allergies of any kind such as allergy toiodine or x-ray contrast material, drugs, food, the environment, or asthma, youneed to inform the doctor in advance. Often doctors use the contrast materialcalled gadolinium that does not contain iodine and is less likely to cause sideeffects or an allergic reaction.If you are having any serious healthissue or have undergone surgery, do inform the radiologist about it. In such cases, doctors may prevent you fromgiving a contrast material for an MRI. Especially if you are suffering fromkidney disease, you may need to perform a blood test to find out whether thekidneys are functioning adequately or not. Patients with metal implant shouldinform the doctor beforehand. Women should inform doctors if they are pregnant. Although there is noevidence of ill effect on pregnant women or their babies, but it is better toavoid this test during pregnancy because, the baby would be exposed to strongmagnetic field.Jewelry and other accessories should be removed prior to the MRI scan becausethey can interfere with the magnetic field of the MRI unit. These are some of the precautions to be takes before and during the MRIscan.
