Whole-body 18F-FDG PET/CT scan in a patient with Lung Cancer taken from the PETWB-REP dataset. The following English report (translated from original Chinese) is taken verbatim from the public dataset and has not been modified or otherwise checked for accuracy (see the end for citation).

Findings

After fasting and intravenous injection of 18F-FDG, a whole-body PET/CT scan was performed.
The whole-body scan showed:Normal brain morphology and structure, with punctate low-density lesions in the deep bilateral cerebral regions; no significant abnormalities in FDG metabolism.
Widening of the ventricles, sulci, fissures, and cisterns; symmetrical bilateral ventricles; no midline shift.
Normal bilateral eyeball morphology and contour; clear retrobulbar structures; symmetrical bilateral optic nerves; no abnormal FDG metabolism.
Slight thickening of the mucosa in parts of the bilateral ethmoid and maxillary sinuses; intact sinus walls; absent FDG metabolism.
No thickening of the nasopharyngeal wall; no stenosis of the bilateral pharyngeal recesses and Eustachian tube openings; normal structures of the infratemporal and pterygopalatine fossae; clear bilateral parapharyngeal spaces; no abnormal FDG metabolism.
Physiological FDG metabolism in the oropharynx and laryngopharynx.
No abnormal contrast enhancement of the bilateral parotid and submandibular glands.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG metabolism is normal.
Several small lymph nodes are visible in the right supraclavicular fossa, the largest being approximately 0.5 cm in short diameter; FDG metabolism is increased, SUVmax = 3.4.
Stenosis at the bronchial opening in the right middle lobe is accompanied by a soft tissue density mass with indistinct borders, measuring approximately 3.8*2.5*4.8 cm in cross-section; FDG metabolism is increased, SUVmax = 21.4.
Most of the middle lobe is atelectasis with localized increased FDG metabolism, SUVmax = 4.0.
The right upper lobe bronchus is compressed; patchy and speckled areas of increased density are seen in the right upper lobe, with slightly increased FDG metabolism in some areas, SUVmax = 1.6.
The remaining two lungs contain scattered solid nodules and calcifications, with regular shapes and clear borders, approximately 0.2-0.5 cm in long diameter; FDG uptake is normal.
A few linear and flocculent density shadows were observed in both lungs, with no abnormalities in FDG metabolism.
No pleural thickening was observed bilaterally, with a small amount of pleural effusion on the right side.
Lymph nodes in the right hilar and mediastinal areas (pretracheal, posterior to the vena cava, aortic window, and subcarinal) were visualized; the largest had a short diameter of approximately 0.9 cm, with increased FDG metabolism and an SUVmax of 4.5.
The cardiac silhouette was normal.
Some arterial walls showed calcification.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan revealed several low-density nodules in the left lobe of the liver, with smooth edges; the largest had a long diameter of approximately 1.6 cm, and no FDG metabolism.
The main portal vein was not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder's shape and size were normal, with no thickening of the gallbladder wall and no abnormalities in local FDG metabolism.
The pancreas is normal in shape, with no obvious abnormal density shadows seen in the parenchyma.
The main pancreatic duct is not widened, and FDG metabolism is normal.
The spleen is normal in shape, size, density, and FDG metabolism.
Both kidneys are normal in shape and size.
A cystic low-density lesion, approximately 0.7 cm in long diameter, is seen in the parenchyma of the lower pole of the right kidney; FDG metabolism is absent.
The renal pelvis, calyces, and ureters are not widened, and FDG metabolism is normal.
Bilateral adrenal glands show no obvious abnormalities on contrast.
The esophagus is not dilated, and the esophageal wall is not significantly thickened or swollen; FDG metabolism is not increased.
The stomach is generally full, with slightly thickened walls; FDG metabolism is increased, with SUVmax = 3.8.
The intestines are poorly full, with no significant thickening or swollen walls; FDG metabolism is physiological.
The prostate is enlarged, with a transverse diameter of approximately 4.8 cm.
High-density shadows are seen within the parenchyma.
FDG metabolism is normal.
The bladder is poorly filled, but no obvious positive stones are seen.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneal region.
No obvious fluid accumulation is seen in the abdomen or pelvis.
The spinal alignment is normal, with osteophyte formation at the margins of some vertebral bodies.
Schmorl's nodes are visible at the lower margin of the T8 vertebral body and the upper margin of the T10 vertebral body.
L4/5 and L5/S1 intervertebral disc bulges are present, but FDG metabolism is normal.
Dense bone shadows are present in the right ischium, but FDG metabolism is normal.

Impression

  1. a. Stenosis at the bronchial opening in the right middle lobe with soft tissue density mass formation and increased FDG metabolism, suggestive of central lung cancer in the right middle lobe with obstructive changes in the right upper and middle lobes. Metastasis to the right hilar, mediastinal, and right supraclavicular fossa lymph nodes. Minimal right pleural effusion. b. Scattered chronic inflammatory nodules and calcifications in the remaining lungs; please follow up with CT scans. A few post-inflammatory remnants in both lungs. Partial arteriosclerosis.

  2. Multiple cysts in the left lobe of the liver. Cyst in the right kidney. Benign prostatic hyperplasia with calcification. (No definite space-occupying lesion seen in the left upper quadrant.)

  3. Chronic gastritis; please follow up with endoscopy.

  4. Degenerative changes in the spine. Schmorl's nodes at the lower margin of the T8 vertebral body and the upper margin of the T10 vertebral body. L4/5 and L5/S1 intervertebral disc bulges. Right ischial insula.

  5. Age-related brain changes, deep lacunar insufficiency in the brain. Minor inflammation of the bilateral ethmoid and maxillary sinuses.

This case is from PETWB-REP, a curated dataset of whole-body 18F-FDG PET/CT scans and corresponding radiology reports from 490 patients with a broad spectrum of malignancies. The data were retrospectively collected from patients who underwent clinically indicated whole-body 18F-FDG PET/CT scans at the Shanghai Universal Medical Imaging Diagnostic Center between 2021 and 2024.
