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

Under fasting conditions, an intravenous injection of 18F-FDG was administered, followed by rest.
Whole-body PET/CT imaging revealed: The brain morphology and structure were normal, with multiple small, patchy low-density shadows in the deep brain parenchyma; FDG uptake was not significantly abnormal.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
FDG uptake was increased in the nasopharyngeal wall (SUVmax = 7.9); the pharyngeal recesses were symmetrical; there was no stenosis of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear, and FDG uptake was not abnormal.
The palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx morphology and structure were normal.
The thyroid gland is normal in shape and size, with uniform density, and no abnormalities were observed in FDG uptake.
Multiple lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region, the largest with a short diameter of approximately 0.6 cm, some showing increased FDG uptake, SUVmax=4.2.
A large area of consolidation was observed in the left lower lobe, with nodular increased uptake near the hilum of the lower lobe, measuring approximately 1.30.9 cm, SUVmax=11.2.
An obstruction of the posterior segment bronchus of the left lower lobe was observed, with localized increased FDG uptake, ranging from approximately 3.72.9 cm, SUVmax=13.9.
Patchy areas of increased density were also observed around the bronchus in the basal segment of the lower lobe, with increased FDG uptake, SUVmax=11.4.
Multiple nodular shadows were also observed in the left lung, with relatively clear borders, the largest with a long diameter of approximately 0.6 cm, and no abnormalities were observed in FDG metabolism.
Scattered linear shadows were observed in both lungs, with no abnormalities in FDG metabolism.
Thickening of the left pleura is visible, but there is no pleural effusion or pneumothorax on either side.
Multiple lymph nodes are seen in the mediastinum, the largest being adjacent to the right trachea, with a short diameter of approximately 0.7 cm.
FDG metabolism is increased, with SUVmax = 5.7.
The cardiac silhouette is normal.
Both breasts are relatively dense, with no abnormal FDG metabolism.
The liver's shape and size are normal, with smooth borders, no widening of the hepatic fissure, and uniformly decreased liver parenchyma density.
Intrahepatic vessels are not clearly visualized.
A small cystic lesion, approximately 0.5 cm in long diameter, is visible adjacent to the gallbladder in the right anterior lobe of the liver, with no abnormal FDG uptake.
The main portal vein is not significantly widened, and no dilation of intrahepatic or extrahepatic bile ducts is observed.
High-density nodules and punctate shadows are visible within the gallbladder lumen, with no abnormal local FDG uptake.
The pancreas is normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct is not widened, and FDG uptake is not significantly abnormal.
The spleen shows no abnormalities in shape, size, density, or FDG uptake.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
The right adrenal gland shows no obvious abnormalities on contrast.
The left adrenal gland is full in shape, with increased FDG metabolism (SUVmax = 2.9).
Increased FDG uptake in the gastric cardia and lower thoracic esophagus (SUVmax = 3.9).
An air-filled cavity is visible in the horizontal part of the duodenum, with physiological FDG uptake.
Multiple high-density nodules are visible around the sigmoid colon, with no abnormal FDG metabolism.
Increased FDG metabolism in the terminal rectum (SUVmax = 13.3).
The uterus is of normal shape, with no abnormal density shadows, and no abnormally increased FDG uptake.
No abnormal FDG metabolism is seen in the bilateral adnexa.
The bladder is generally full, with no obvious positive stones.
Multiple lymph nodes are seen in both inguinal regions, the largest with a short diameter of approximately 0.7 cm, some with increased FDG metabolism, SUVmax=3.7.
No obvious fluid accumulation is seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body marginal osteophytes, slight anterior displacement of the L4 vertebral body, and L4/5 intervertebral disc bulging, but no abnormal FDG uptake is seen.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. A mass in the lower lobe of the left lung with increased FDG metabolism, suggestive of lung cancer with surrounding obstructive inflammation and mediastinal lymph node metastasis. Please correlate with clinicopathology. b. Multiple chronic inflammatory nodules in the left lung, some with metastatic involvement to be ruled out. Follow-up CT scan recommended. A few remnants of chronic inflammation in both lungs. Slight thickening of the left pleura.

2. Increased FDG metabolism in the nasopharyngeal wall, suggestive of inflammation. Specialist examination recommended if necessary.

3. a. Increased FDG uptake in the gastric cardia and lower thoracic esophagus, suggestive of inflammation or physiological uptake. Endoscopic follow-up recommended. b. Diverticulum in the horizontal part of the duodenum. Multiple small diverticula in the sigmoid colon. Increased FDG metabolism in the terminal rectum, suggestive of hemorrhoids or physiological uptake. Please correlate with clinical findings.

4. Fatty liver, small cyst beside the gallbladder in the right anterior lobe of the liver. Gallstones. Left adrenal hyperplasia. Multiple reactive hyperplasia of lymph nodes in both groins.

5. Spinal osteophyte formation, with mild anterior slippage of the L4 vertebral body. L4/5 intervertebral disc bulge.

6. Multiple ischemic lesions deep in the brain parenchyma; MRI examination may be necessary. Multiple reactive hyperplasia of lymph nodes in the bilateral deep cervical spaces, submandibular region, and submandibular region.

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.
