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 uniform density, and no abnormalities were observed in FDG metabolism.
No significantly enlarged lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, or submental region.
An irregular soft tissue density mass, approximately 4.2*3.2cm in cross-section, was observed in the posterior segment of the left upper lobe near the hilum.
FDG metabolism was elevated, with an SUVmax of 6.4, and spiculated shadows were observed around the mass.
Multiple ground-glass opacities were observed in both lungs, with relatively clear borders, most prominent in the apical segment of the right upper lobe, the posterior segment of the left upper lobe, and the right middle lobe.
Their sizes were approximately 1.7*2.1cm, 2.0*1.9cm, and 0.7*0.6cm, respectively.
Some showed mildly elevated FDG metabolism, with an SUVmax of 2.1.
Several small, solid nodules were observed in the right middle lobe and both lower lobes.
These nodules were regular in shape, with clear borders, and a long diameter of approximately 0.2?.4 cm.
FDG uptake was normal.
A patchy, hazy shadow was observed in the left lower lobe, with increased FDG metabolism (SUVmax = 2.6).
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax.
A slightly enlarged lymph node was observed in the left hilum, with a short diameter of approximately 0.8 cm.
FDG metabolism was increased (SUVmax = 3.6).
The cardiac silhouette was normal.
Some arterial walls showed calcification.
The left breast showed slightly dense fibrous glands, with normal FDG metabolism.
No obvious masses or nodules were observed in the right breast, and FDG metabolism was normal.
The liver showed no obvious abnormalities in shape or size, with smooth borders and no widening of the hepatic fissure.
A slightly low-density shadow was observed in the right lobe of the liver, with a long diameter of approximately 1.0 cm.
FDG metabolism was normal.
The main portal vein showed no significant widening, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The gallbladder appeared normal in shape and size, with no thickening of the gallbladder wall and no abnormalities in local FDG metabolism.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma, no widening of the main pancreatic duct, and no obvious abnormalities in FDG metabolism.
The spleen showed no abnormalities in shape, size, density, or FDG metabolism.
Both kidneys were normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters were not widened, and FDG metabolism was not significantly abnormal.
Bilateral adrenal gland contrast was normal.
The esophagus showed no dilation, no significant thickening or mass in the esophageal wall, and no increased FDG metabolism.
The stomach was poorly filled, with slight thickening of the gastric wall and a slightly increased FDG metabolism; SUVmax = 1.8.
Intestinal distension is poor, with no obvious thickening or mass in the intestinal wall; FDG metabolism is physiological.
The uterus is normal in shape and size, with calcification on the right wall of the uterine fundus; FDG metabolism is normal.
No obvious abnormalities are seen in the bilateral adnexa.
The bladder is poorly distended, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdomen, pelvis, or retroperitoneum.
No obvious fluid accumulation is seen in the abdomen or pelvis.
Mild scoliosis is present, but the spinal alignment is normal.
Calcification of the nuchal ligament and osteophyte formation at the margins of some vertebral bodies are observed.
L4/5 and L5/S1 intervertebral disc bulges are present; FDG metabolism is normal.
Slightly blurred bone is observed in the right iliac bone; FDG metabolism is slightly elevated, with SUVmax = 2.3.

Impression

1. a. A mass near the hilum in the apical-posterior segment of the left upper lobe, with increased FDG metabolism, suggestive of lung cancer. Left hilar lymph node metastasis cannot be ruled out. b. Multiple ground-glass opacities in both lungs, some with mildly increased FDG metabolism, highly suggestive of atypical adenomatous hyperplasia, with the largest nodules in the apical segment of the right upper lobe, the apical-posterior segment of the left upper lobe, and the right middle lobe. Early-stage tumors need to be ruled out; regular CT scans for comparison are recommended. c. Several small chronic inflammatory nodules (solid) in the right middle lobe and both lower lobes; mild inflammatory changes in the left lower lobe; follow-up CT scan is recommended. Some arteriosclerosis. Left breast hyperplasia. d. Slightly blurred local bone structure in the right iliac bone, with slightly increased FDG metabolism; follow-up MRI is recommended to rule out metastasis.

2. Calcification at the fundus of the uterus.

3. Slightly low-density lesion in the right lobe of the liver; FDG metabolism normal; suggestive of cyst or hemangioma; MRI recommended. Chronic gastritis.

4. Mild scoliosis; degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge.

5. Age-related brain changes; deep lacunar infarcts in the brain; MRI recommended. Minor inflammation of 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.
