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: A few punctate low-density shadows were seen in the deep bilateral cerebral regions; no abnormal density shadows were seen in the remaining brain parenchyma.
FDG uptake was normal.
The ventricles, sulci, fissures, and cisterns were widened; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical, with no obvious abnormalities.
The mucosa of the bilateral maxillary and ethmoid sinuses was thickened, but the sinus walls were intact.
The nasopharyngeal wall was not thickened, and FDG uptake was normal.
The bilateral pharyngeal recesses were symmetrical, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear with no abnormal FDG uptake.
The bilateral palatine tonsils showed physiological uptake.
No abnormal density shadows were seen in the bilateral parotid and submandibular glands.
The morphology and structure of the laryngopharynx were normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
Focal FDG uptake is observed in the genioglossus muscle, SUVmax=8.2; no enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
An irregular mass measuring approximately 4.23.73.1cm is seen in the apical-posterior segment of the left upper lobe, with lobulated and spiculated margins; FDG uptake is increased, SUVmax=12.8.
There is bronchial occlusion in the apical-posterior segment of the left upper lobe; thickening of the interlobular septa in the left upper lobe is accompanied by multiple patchy and flocculent opacities; FDG uptake is increased, SUVmax=5.9; several solid micronodules are observed in both lungs, with a long diameter of approximately 0.2-0.4cm and clear borders; FDG uptake is normal.
A few punctate lesions, calcifications, and linear lesions are also seen in both lungs; FDG uptake is normal.
A small amount of pleural effusion is present in the left side.
Multiple enlarged lymph nodes were observed in the bilateral pulmonary hila, pretracheal space, para-aortic arch, aortopulmonary window, subcarinal region, and left supraclavicular fossa.
The largest lymph node had a short diameter of approximately 2.3 cm.
FDG metabolism was increased, with SUVmax = 9.6.
The cardiac silhouette was normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus was not dilated, and the wall showed no significant thickening or mass; FDG uptake was not increased.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Plain CT scan showed no significant abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein was not significantly widened, and no dilation was observed in the intrahepatic or extrahepatic bile ducts.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma.
The pancreatic duct was slightly dilated, and FDG uptake was normal.
The spleen's shape, size, density, and FDG uptake were normal.
Both kidneys are normal in shape and size, with no obvious abnormal density shadows seen in the parenchyma.
The renal pelvis, calyces, and ureters are not widened, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no obvious abnormalities.
The stomach is poorly filled, with slight thickening of the walls of the gastric fundus, part of the gastric body, and antrum.
FDG uptake is increased, SUVmax=3.6.
The intestines are poorly filled, with no intestinal wall thickening or masses seen.
The prostate is full in shape, with a transverse diameter of approximately 5.2 cm, uniform density, and increased FDG metabolism in the peripheral zone, SUVmax=5.6.
The bladder is generally full, with no obvious positive stones seen.
No enlarged lymph nodes were seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation was seen in the abdominal or pelvic cavities.
The spinal alignment is normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Mass in the posterior segment of the left upper lobe, with increased FDG metabolism, suggestive of lung cancer with obstructive changes; carcinomatous lymphangitis of the left upper lobe. b. Multiple lymph node metastases in the left hilum, mediastinum, and left supraclavicular fossa. Chronic inflammatory lymph nodes in the right hilum. c. Several small (solid) chronic inflammatory nodules in both lungs. A small amount of chronic inflammation and old lesions in both lungs. d. Small amount of pleural effusion on the left side. Calcification of some arterial walls (including coronary arteries).

2. Slight thickening of the gastric fundus, part of the gastric body, and antrum walls, with increased FDG uptake, suggestive of chronic gastritis; follow-up with gastroscopy is recommended.

3. Mild dilatation of the pancreatic duct. Benign prostatic hyperplasia, with increased FDG metabolism in the peripheral zone, suggestive of inflammatory or physiological uptake; follow-up with PSA and ultrasound is recommended.

4. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulges.

5. A few ischemic foci in the deep bilateral cerebral regions, indicative of age-related brain changes. Chronic inflammation of the bilateral maxillary and ethmoid sinuses. Focal FDG hypermetabolism in the genioglossus muscle, suggestive of stress-induced uptake.

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.
