Brain and blood vessels 6
Brain arteries (MRA)
All the main arteries feeding the brain look normal. No aneurysm, no blockage, no malformed vessels.
NormalAneurysm
None
Stroke, bleeding and tumor check
No sign of an old or recent stroke, bleeding, mass or MS-type disease.
ClearBrain
Clear
White matter spots
Several very small spots in the frontal and parietal lobes. These are commonly linked to high blood pressure (or migraines), so it is another reason to keep BP tight.
WatchSpots
Several, tiny
Fluid space in the middle of the brain
Cavum septum pellucidum and vergae: a small fluid pocket left over from before birth. A common normal variant. Mildly widened; only matters if there are headaches.
VariantType
Normal variant
Mineral deposits (basal ganglia)
Minimal mineralization deep in the brain. A benign, age-related finding.
Age-relatedAmount

Eyes, ears and sinuses
Prior cataract surgery in both eyes. Otherwise eyes, optic nerves, inner ears and sinuses are normal.
NormalSinuses
Clear
Neck 3
Thyroid nodules
Three smooth, benign-looking nodules: right side 1.1 cm and 0.3 cm, left side 0.4 cm. The radiologist says no further workup is needed.
BenignLargest
1.1 cm
Neck spine (cervical)
Wear and tear. Bone and disc touch the spinal cord but do not compress it; up to moderate canal narrowing and severe narrowing of the nerve openings on both sides. No damage to the cord. Matters if there is neck pain or arm/hand numbness or tingling.
Ask doctorNerve openings
Severe narrowing
Glands, lymph nodes and airway
Salivary glands, vocal cords, windpipe and esophagus normal. No enlarged lymph nodes.
NormalLymph nodes

Heart and aorta
Heart is a normal size. Chest aorta and surrounding structures look normal.

Grade 1 slip (anterolisthesis) of the bottom lumbar vertebra, with long-standing stress cracks (pars defects) on both sides of L5.
WatchGrade

Lower-back wear
No significant canal narrowing, but up to moderate narrowing of the nerve openings. Small tears in the outer rings of the discs from L2 to S1. Matters if there is back pain or leg symptoms.
WatchNerve openings
Up to moderate
Pelvis 4
Rectum lining
Mild swelling and thickening of the rectal lining, which the radiologist thinks is inflammation (proctitis). Hard to judge without contrast; a pelvic MRI with contrast is an option if the doctor thinks it is needed.
