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 scan showed: A soft tissue nodule, approximately 2.7*1.7cm in cross-section, was observed in the sellar region, with increased FDG uptake (SUVmax = 5.2).
A few punctate low-density shadows were seen in the deep bilateral cerebral regions, with no significant abnormalities in FDG uptake.
The ventricles, sulci, fissures, and cisterns were widened, with symmetrical bilateral ventricles and no midline shift.
Both eyeballs were symmetrical, with no significant abnormalities.
No thickening of the paranasal sinus mucosa was observed, and the sinus walls were intact.
No thickening of the nasopharyngeal wall was observed, with no abnormal FDG uptake.
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 are normal.
The thyroid gland is normal in shape and size, with slightly uneven density; FDG uptake is normal.
No enlarged lymph nodes are seen in the bilateral deep cervical spaces or submandibular region.
Increased translucency of both lungs, with multiple air-filled cavities.
A mixed-density ground-glass nodule measuring approximately 1.6 2.2 cm is seen in the posterior segment of the left lower lobe, with increased FDG metabolism (SUVmax = 1.8).
Another ground-glass nodule is seen in the anteromedial basal segment of the left lower lobe, with a CT value of approximately -549 HU, a long diameter of approximately 0.7 cm, relatively clear borders, and normal FDG metabolism.
Several small solid nodules are seen in both lungs, with long diameters of approximately 0.2?.5 cm, clear borders, and normal FDG metabolism.
A few linear and punctate lesions are also seen in both lungs, with normal FDG metabolism.
No pleural thickening is seen bilaterally, and there is no pleural effusion or pneumothorax.
Several small lymph nodes, approximately 0.5 cm in short diameter, were observed in both pulmonary hilum and mediastinum.
FDG metabolism was normal.
Cardiac findings were normal.
Calcification was observed in some arterial walls (including the coronary arteries).
The esophagus showed no dilation, no significant thickening or mass in the wall, and no increased FDG uptake.
The liver's shape and size were normal, with smooth borders and no widening of the hepatic fissure.
Multiple cystic lesions were observed within the liver, the largest approximately 2.5 cm in long diameter, with absent FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts.
The gallbladder was absent post-operatively.
The pancreas was normal in shape, with no significant abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, 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 multiple cystic low-density lesions in both kidneys, the largest being in the left kidney, with a long diameter of approximately 1.6 cm.
FDG uptake is absent.
No widening of the renal pelvis, calyces, or ureter is observed, and FDG uptake is not significantly abnormal.
Bilateral adrenal gland imaging shows no significant abnormalities.
The stomach is poorly distended, with slight thickening of the antral wall and mildly increased FDG uptake (SUVmax = 2.3).
Intestinal distension is unsatisfactory, with continuous increased FDG metabolism in parts of the colon and rectum (SUVmax = 4.5).
An air-filled cavity is seen in the descending duodenum, with no abnormal FDG metabolism.
The prostate is normal in shape and size, with punctate calcifications observed, and no abnormal FDG metabolism.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvic cavity, or retroperitoneal region.
No significant fluid accumulation is 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.
Increased FDG uptake in the L3/4 interspinous region, SUVmax = 2.8.
Decreased bone mineral density in all bones.
No abnormalities were observed in systemic bone marrow FDG metabolism.

Impression

1. a. Mixed-density ground-glass nodule in the posterior segment of the left lower lobe, with mildly increased FDG uptake, suggestive of peripheral lung cancer. b. Ground-glass nodule in the anterior-interior basal segment of the left lower lobe, with normal FDG uptake, suggestive of atypical adenomatous hyperplasia, early lung cancer to be ruled out. c. Several small chronic inflammatory nodules (solid) in both lungs. A few chronic inflammations and old lesions in both lungs. Emphysema with bullae in both lungs. Reactive hyperplasia of hilar and mediastinal lymph nodes in both lungs. Calcification of some arterial walls (including coronary arteries).

2. Sellar region mass, increased FDG uptake, suggestive of pituitary adenoma, metastasis to be ruled out; enhanced MRI is recommended for further examination.

3. Multiple liver cysts. Bilateral renal cysts. Prostatic calcifications.

4. Chronic antral gastritis. Increased continuous FDG metabolism in parts of the colon and rectum, suggestive of inflammatory or physiological uptake. Duodenal diverticulum.

5. Osteoporosis. Degenerative changes in the spine. L4/5 and L5/S1 intervertebral disc bulge. Inflammatory uptake in the L3/4 interspinous region.

6. A few ischemic foci in the deep bilateral brain regions, age-related brain changes.

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.
