[Verse 1]
Chest, belly, pelvis — the camera makes its rounds,
One long axial sweep and the shadow's finally found.
But when the pancreas whispers trouble, we slow the dial down,
Pancreatic protocol, timed phases, tracing every vessel's crown.
Watch the celiac axis, the SMA, the SMV too,
If the tumor's wrapped around them, that's the verdict coming through —
Surgery or standstill, the vessels hold the key,
A borrowed hallway through the gut, blocked or running free.
[Verse 2]
CT paints the landscape, but soft tissue needs finer eyes,
MRI slides in closer where the gray and white disguise.
Rectal cancer's measured by a fascia thin as thread,
Mesorectal margin — how close the danger's spread.
Liver lesions hiding in the blur of fat and bile,
Sarcoma's tangled fibers caught in magnet's patient trial,
And up inside the skull where no scalpel dares to peek,
MRI reads the brain's quiet architecture, week to week.
[Chorus]
CT maps it, MRI frames it,
PET lights up what sugar claims,
EUS leans in nose to nose —
Four ways imaging knows what it knows.
Slice it, trace it, measure twice,
Before a single knife meets flesh or ice,
The picture talks, the stage gets named,
T and N and M — the tumor's framed.
[Verse 3]
PET scan feeds on glucose, greedy cells light up like coals,
But fevers, scars, and healing wounds can fake those hungry glows —
A false alarm from infection, inflammation playing tricks,
While mucinous tumors stay dim, slow growers hide their kicks.
Some liver cancers whisper low, almost refuse to shine,
So PET alone won't tell the story — read between each line.
It's a clue, not gospel, a glowing hint, not fact,
Pair it with the structure scans to know how cells react.
[Verse 4]
Now slide the scope down softly, ultrasound upon its tip,
Esophagus and stomach, rectum, pancreas — the trip
Measures depth of invasion, nodes along the way,
T and N decided close, no guessing where they lay.
And in the breast, the answer comes in numbers, clean and plain,
BI-RADS zero up to six — a scorecard, not a stain,
Zero's incomplete, six is cancer, proven, known,
Each category a signpost on the road to what is grown.
[Bridge]
Every scan's a sentence in the body's quiet book,
TNM the grammar — size, and spread, and where to look.
Resectable or hopeless, the pictures draw the line,
Before the surgeon's hand decides what's yours and what's benign.
[Chorus]
CT maps it, MRI frames it,
PET lights up what sugar claims,
EUS leans in nose to nose —
Four ways imaging knows what it knows.
Slice it, trace it, measure twice,
Before a single knife meets flesh or ice,
The picture talks, the stage gets named,
T and N and M — the tumor's framed.
[Outro]
Four lenses, one story, written in gray and white,
Read it clear before you cut — let the pictures hold the light.
