Essential Reading! Get my first book: The Only Sale Guide You’ll Ever Need “The USA Today bestseller by the star sales speaker and author of The Sales Blog that reveals how all salespeople can attain huge sales success through strategies backed by extensive research and experience.” Buy Now The dream client you’ve been pursuing has once again rejected your request for a meeting. You have asked so many times that you have lost count of how much this contact has told you “No.” You want to believe that “no” doesn’t mean “no,” that it means “maybe,” or “later,” or something.And then you stop calling this prospect. They’re just too difficult. You give up.A Step Onto the Slippery SlopeYou’ve been calling another dream client. You haven’t called them nearly as often as you called the first dream client, the one you decided to quit pursuing. But this prospect is no different. They won’t give you the time of day, and they continually reject your request for a meeting out of hand.Even though you’ve made only half the attempts to reach this client as the first prospect, you decide it’s hopeless. So you stop calling and move on to lower hanging fruit.Spiraling DownwardAnother dream client has taken your calls. But she’s always said “no” to each and every one of your requests for a meeting. She’s nice, polite, and professional, but she always says “no.” Honestly, you haven’t made anywhere near as many attempts to schedule a meeting with this prospect as you have the other two.You decide that this prospect is just like the other two, and you decide to discontinue calling her. You have better things to do with your time.Slowly, imperceptibly, you have trained yourself to take “no” for an answer. You’ve allowed yourself to give up the discomfort of persistence for the conflict-free role of pushover.The pursuit of your dream clients is a game with no time limit. You don’t have to win now. You don’t even have to win their business next quarter. You just have to win their business eventually. If you keep giving up every time a prospect says “no,” how long will it be before you eliminate all of the dream clients in your territory?The mark of the professional is their willingness to persist.
DefinitionA knee MRI (magnetic resonance imaging) scan uses energy from strong magnets to create pictures of the knee joint and muscles and tissues.An MRI does not use radiation (x-rays). Single MRI images are called slices. The images can be stored on a computer or printed on film. One exam produces many images.Alternative NamesMRI – kneeHow the test is performedYou will wear a hospital gown or clothes without metal zippers or snaps (such as sweatpants and a t-shirt). Certain types of metal can cause blurry images.You will lie on a narrow table that slides into a large tunnel-like scanner.Some exams use a special dye (contrast). Most of the time, you will get the dye through a vein (IV) in your arm or hand before the test. Sometimes, the dye is given into a joint. The dye helps the radiologist see certain areas more clearly.During the MRI, the person who operates the machine will watch you from another room. The test most often lasts 30-60 minutes, but may take longer.How to prepare for the testYou may be asked not to eat or drink anything for 4 – 6 hours before the scan.Tell your doctor if you are afraid of close spaces (have claustrophobia). You may be given a medicine to help you feel sleepy and less anxious. Your doctor may suggest an “open” MRI, in which the machine is not as close to the body.Before the test, tell your health care provider if you have:advertisementBrain aneurysm clipsCertain types of artificial heart valvesHeart defibrillator or pacemakerInner ear (cochlear) implantsKidney disease or dialysis (you may not be able to receive contrast)Recently placed artificial jointsCertain types of vascular stentsWorked with sheet metal in the past (you may need tests to check for metal pieces in your eyes)Because the MRI contains strong magnets, metal objects are not allowed into the room with the MRI scanner:Pens, pocketknives, and eyeglasses may fly across the room.Items such as jewelry, watches, credit cards, and hearing aids can be damaged.Pins, hairpins, metal zippers, and similar metallic items can distort the images.Removable dental work should be taken out just before the scan.How the test will feelAn MRI exam causes no pain.You will need to lie still. Too much movement can blur MRI images and cause errors.The table may be hard or cold, but you can ask for a blanket or pillow. The machine makes loud thumping and humming noises when turned on. You can wear ear plugs to help block out the noise.An intercom in the room allows you to speak to someone at any time. Some MRIs have televisions and special headphones to help the time pass.There is no recovery time, unless you were given a medicine to relax. After an MRI scan, you can return your normal diet, activity, and medicines.Why the test is performedYour doctor may order this test if you have:An abnormal result on a knee x-ray or bone scanA feeling that your knee is giving away in the knee jointBuildup of joint fluid behind the knee (Bakers cyst)Fluid collecting in the knee jointInfection of the knee jointKnee cap injuryKnee pain with feverKnee locking when you walk or movingSigns of damage to the knee muscle, cartilage, or ligamentsKnee pain that does not get better with treatmentYou may also have this test to check your progress after knee surgery.Normal ValuesA normal result means your knee looks okay.What abnormal results meanAbnormal results may be due to a sprain or tear of the ligaments in the knee area.Abnormal results may also be due to:Arthritis of the kneeAvascular necrosis (also called osteonecrosis)Bone tumor or cancerBroken boneBuildup of joint fluid behind the knee (Bakers cyst)Infection in the bone (osteomyelitis)InflammationInjury of the knee capTalk to your health care provider if you have questions or concerns.What the risks areMRI contains no radiation. There have been no reported side effects from the magnetic fields and radio waves.The most common type of contrast (dye) used is gadolinium. It is very safe. Allergic reactions to the substance are rare. However, gadolinium can be harmful to people with kidney problems that need dialysis. If you have kidney problems, please tell your health care provider before the test.The strong magnetic fields created during an MRI can cause heart pacemakers and other implants to not work as well. It can also cause a piece of metal inside your body to move or shift. For safety reasons, please dont bring anything that contains metal into the scanner room.advertisementSpecial considerationsTests that may be done instead of a knee MRI include:CT scan of the kneeKnee x-rayReferencesWilkinson ID, Paley MNJ.
