LUMBAR STENOSIS RATES AS INDICATED BY MRI INTERPRESTATION RANGED BETWEEN 38.5% IN RECUMBENT (LAYING DOWN) SCANS AND 56.7% IN WEIGHT-BEARING (UPRIGHT) MRI. THESE RATES ARE HIGHER THAN THOSE REPORTED IN THE MEDICAL LITERATURE IN ASYMTOMATIC PATIENS.

IMAGING IN THE POSITION THAT CAUSES PAIN-MRI OF THE CERVICAL SPINE IN THE POSITION OF THAT CAUSES THE PATIENT’S SYMPTOMS MAY INCREASE THE SENSITIVITY AND ACCURACY OF THE DIAGNOSTIC STUDY AND THUS PROVIDE THE SPINE-CARE PROFESSIONAL WITH A POTENTIALLY MORE ACCURATE DIAGNOSIS AND A TARGETED TREATMENT PLAN.

IMAGING THE SPINE IN THE WEIGHT-BEARING (UPRIGHT) POSITION WITH EXTENSION OR PLACING THE SPINE IN THE POSITION OF PAIN MAY INCREASE THE DIAGNOSTIC ACCURACY BY THE RADIOLOGIST WHO CAN THEN PROVIDE THE SPINE SURGEON OR NEUROSURGEON WITH ADDITIONAL INFORMATION TO FURTHER IMPROVE PATIENT CARE.

POSITIONAL MRI (UPRIGHT) OFFERS THE ADVANTAGES OF ASSESSING CERVICAL SPINE PATHOLOGY IN NEUTRAL, FLEXION AND EXTENSION POSITIONS. POSITIONAL MRI ALLOWS EXAMINATION OF THE CERVICAL SPINE IN A MORE PHYSIOLOGIC, WEIGHT-BEARING POSITION AS COMPARED TO TRADITIONAL SUPINE(LAYING DOWN) MRI’S.

WHEN PATIENTS WITH NON-CANCER, LOWER BACK PAIN WORSEN, FAIL TO IMPROVE OR REQUIRE OPIATES TO MANAGE THEIR PAIN, UPDATED CLINICAL DIAGNOSIS INCLUDING REPEAT POSITIONAL IMAGING (UPRIGHT MRI) MAY BE AN EFFECTIVE DIAGNOSTIC STRATEGY.

MISSED LUMBAR DISC HERNIATIONS DIAGNOSED WITH KINETIC (FLEXION AND EXTENSION) MRI. A SIGNIFICANT INCREASE IN THE DEGREE OF LUMBAR DISC HERNIATINS WERE FOUND BY EXAMINING FLEXION AND EXTENSION VIEWS WHEN COMPARED WITH NEURTAL VIEWS ALONE. Kmri (FLEXION/EXTENSION) VIEWS PROVIDE VALUABLE ADDED INFORMATION, ESPECIALLY IN SITUATIOINS WHERE SYMPTOMATIC RADICULOPATHY IS PRESENT WITHOUT ANY ABNORMALITIES DEMONSTRATED ON CONVENTIONAL MRI (LAYING DOWN).

EFFECT OF SAGITTAL ALIGNMENT ON KINEMATIC CHANGES AND DEGREE OF DISC DEGENERATIONIN THE LUMBAR SPINE: AN ANALYSIS USING POSITIONAL MRI (UPRIGHT). CHANGES IN SAGITTAL ALIGNMENT MAY LEAD TO KINEMATIC CHANGES IN THE LUMBAR SPINE. THIS MAY SUBSEQUENTLY INFLUENCE LOAD BEARING AND THE DISTRIBUTION OF DISC DEGENERATION AT EACH LEVEL. SAGITTAL ALIGNMENT, DISC DEGENERATION AND SEGMENTAL MOBILITY LIKELY HAVE A RECIPRICAL INFLUENCE ON EACH OTHER.

UPRIGHT -SEATED MRI WAS FOUND TO BE SUPERIOR TO RECUMBENT(LYING DOWN) MRI OF THE SPINE WITH RUCUMBENT MRI MISSING OR UNDERESTIMATING PATHOLOGY IN CASES OF POSTERIOR DISC HERNIATIONS AND ANTERIOR SPONDYLOLITHEISIS. THIS SEEMS TO VALIDATE THE IMPORTANCE OF WEIGHT-BEARING IMAGING OF THE SPINE THAT MIGHT BE EXPECTED TO UNMASK POSTIONAL ENLARGING DISC HERNIATIONS AND WORSENING SPONDYLOLISTHESIS.

THE BENEFICIAL ASPECTS OF UPRIGHT WEIGHT BEARING AND DYNAMIC-KINETIC SPINAL IMAGING OVER RECUMBENT MRI INCLUDE: THE REVELATION OF OCCULT DISEASE DEPENDENT ON AXIAL LOADING, THE UNMASKING OF KINETIC-DEPENDENT(FLEXION AND EXTENSION) DISEASE, AND THE ABILITY TO SCAN THE PATIENT IN THE POSITION OF CLINICALLY RELEVANT SIGNS AND SYMPTOMS.
