Needle Localizations

SMIL offers a needle localization exam for the breasts in Scottsdale and Gilbert, Arizona. A needle localization exam of the breast is done when another breast exam shows breast lumps or abnormalities. A needle localization of the breast is a pre-surgical procedure in which a wire is inserted via a hollow needle into the breast to localize (pinpoint) either a mass or calcifications which may not be felt on physical examination.

During a needle localization exam of the breasts, imaging is used to place a needle next to an abnormal area in the breast. Then, in the operating room, the surgeon uses the wire as a guide and can remove both the abnormal area and the wire.

The Radiologist will numb the area of your breast with a local anesthetic and insert a localization needle into your breast, pointing toward the spot that needs to be biopsied. The Radiologist will then take more images to confirm the position of the needle and withdraw the needle leaving the wire behind. One last mammogram image will be taken to confirm the placement of the wire.

Needle localization of the breasts typically takes thirty minutes to perform before a patient goes to surgery.

I had a great experience getting my CT scan here. The paperwork process was very convenient because I was able to complete everything online before my appointment. The instructions provided ahead of time were clear and easy to follow, which helped me feel prepared. When I arrived, the entire process was quick and efficient. The staff was friendly, helpful, and made sure I felt comfortable throughout my visit. Everyone was professional and willing to answer any questions I had, making what could have been a stressful experience much easier. I would highly recommend this facility to anyone needing imaging services. Thank you to the staff for providing such excellent care and making the process smooth from start to finish.

Their radiologist and other technicians are great. However, the Bureaucrats handling appointments and orders from doctors need more training, or just don't care about the old people like me that have difficulty walking and showing up to their imaging. I showed up today in the morning without an appointment because my cardiologist gave me an appointment in two days, and they couldn't find the order for my X-rays or they don't accept walk-ins. I got a call later to come back after someone found the order, waste of gasoline and my limited walking as I wait for my hip replacement. That's very inconsiderate of these Bureaucrats. I used to supervise government Bureaucrats and I always pressed on the importance of the public and their satisfaction with the service. These people either need training, their management doesn't care, or they're complacent with their business model. But it shows that the left hand doesn't know what the right hand it's doing

Had a great experience at this SMIL location for an MRI. The check-in process was very efficient with minimal wait time. And the techs Sidney & Melana were awesome, so friendly & professional. Sidney has serious IV skills, I usually have trouble but I didn't even feel the stick. They talked me through the whole thing, will def make future appointments at this location.
