Ahhh…summertime. Warm weather means outdoor sports, vacations, exercise and …shoulder injuries? That’s right, shoulder injuries. Many classic outdoor activities during the summer months are “overhand/overhead” ones like baseball, softball, tennis, swimming volleyball or even painting, roofing and yard work.
While all these activities use different muscles, they all involve repetitive use of the shoulder that can lead to potential shoulder instability (when the shoulder joint is loose and slides around too much in the socket). This repetitive motion can cause the shoulder ligaments to loosen and in some cases, slip out and dislocate or lead to arthritis. Frequent use of the shoulder can also cause severe problems with the rotator cuff.
The rotator cuff is the name for four distinct muscles and their tendons that surround the shoulder, that provide strength and stability during motion. Some of the most common shoulder conditions to the rotator cuff that can occur in the warmer months include impingement syndrome, bursitis, tendinitis and tendon ruptures or tears. All of these can vary in severity and if ignored, can aggravate the shoulder even further. One of the top injuries that we see at Shields MRI during the summer season is rotator cuff tears. So how do you know if you have a rotator cuff tear and if you need an MRI?
First thing is first –any concerns, sharp pains or prolonged discomfort is a reason to visit your doctor; and a doctor that specializes in orthopedics is one that can help address concerns with your shoulder and rotator cuff.
Dr. Mayo Noerdlinger, an Orthopaedic surgeon at Atlantic Orthopaedics and Sports Medicine in Portsmouth, New Hampshire, advises on why MRI may be recommended for a rotator cuff tear. “To simplify matters, rotator cuff tears do not heal; they can retract, leading to muscle atrophy and eventually cause arthritis in the shoulder. For these reasons, I tend to order MRIs to evaluate the rotator cuff when someone presents with ongoing shoulder pain and weakness.”
MRI is particularly beneficial for internal organs, muscles, connective tissue and the central nervous system and uses cross-sectional imaging to create extremely clear and detailed picture, allowing your physician to make an earlier and accurate diagnosis. In the instance of a rotator cuff injury, your doctor may recommend an MRI not only to diagnosis a tear, but rather, to exclude the possibility of one.
Not all shoulder pain and injury to the rotator cuff is cause for an MRI. Dr. Noerdlinger explains, “Only three things will limit external rotation: arthritis, a posteriorly dislocated shoulder and frozen shoulder. Both arthritis and a posteriorly dislocated shoulder can be diagnosed on plain x-ray. The best way to evaluate for a frozen shoulder is to assess the external rotation of a patient's glenohumeral joint. A frozen shoulder is the presumed diagnosis in the setting of normal X-rays and limited external rotation."
Dr. Noerdlinger describes a very simplified method he uses when he is considering an MRI for a patient complaining of pain and discomfort in their shoulder. “Pain and weakness with good passive range of motion, consider a MRI to rule out a rotator cuff tear. Pain and weakness with poor passive range of motion (especially external rotation), consider a glenohumeral cortisone injection and physical therapy to treat the frozen shoulder.”
If your doctor does recommend an MRI for your shoulder, there are two potential types of MRI procedures that can be used to diagnose a rotator cuff tear: A routine shoulder MRI, which takes about 25 minutes of actual scan time, and shoulder MR arthrogram, which involves an X-ray procedure during which contrast is injected directly into the shoulder joint space followed by an MRI. An MR arthrogram is more specific for shoulder joint injuries, but is also more involved and requires the patient to be at the facility for about two hours. Your doctor can help determine which scan is the right one for your injury. Example images of shoulder injuries for both types of MRI scans are shown below.
Shields MRI, chief technologist, Aaron Easton says, “ As with any injury, it is critical that the patient is comfortable and relaxed during their MRI. Not only does this create a better imaging experience, but it ensures that the patient is still to obtain the best images possible. An important thing to remember when imaging the shoulder is that MRI is very sensitive to motion; the challenge with the shoulder is its very close proximity to the lungs. Breathing calm and relaxed and avoiding heavy breathing, coughing and clearing of the throat during the imaging sequences will all help to ensure image quality. At Shields MRI, our staff will use cushions and padding to support our patients’ arms and legs as a way to make them as comfortable as possible and make it easier to remain still throughout the exam.”
If you are experiencing any pain that is consistent with the descriptions in this article, you may want to consider a visit to your doctor, who may recommend therapy, rehabilitation or an MRI. The biggest lesson is to listen to your body and your doctor. And if we see you at Shields MRI, we’ll do everything we can to get you back on the playing field without further pain or injury.

Most people will agree that the word “fun” doesn’t pop into their head when finding out they need to have an MRI scan. The majority of patients will be concerned with both their comfort during the scan and correctly diagnosing the injury. Some patients will think that the open style of a machine will leave them more at ease. However, the true source of a better experience is the core of the machine, the magnet. At Shields, we provide both with our 1.5T and 3T wide, open bore MRI machines.

Taking an active role in your health and communicating with your doctor is critical to getting good healthcare; that includes discussions around cost. Here are some tips on preparing for discussions with your doctor about price.
Get educated. Before you go to your appointment, become familiar with your health plan. Find out about your co-pay, deductible and what procedures are covered.
As the New England Patriots place Stephen Gostkowski on the injured reserve due to a torn quadricep & Shayne Graham steps in as the #1 kicker, folks are asking what does a tear look like on an MRI?
Virtual colonoscopy (VC) is an examination of the large intestine and rectum involving a CT scan after the introduction of gas into the colon. Another name for the procedure is CT colonography.
Generally speaking you can get a high-quality MRI scan in a comfortable setting regardless of your body size. Access to care is not driven by body size though your personal comfort may come into play. In fact, professional athletes of all shapes and sizes have completed an MRI scan or two!
