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 were observed in FDG uptake.
The ventricles, sulci, fissures, and cisterns were slightly widened; the ventricles were symmetrical, and there was no midline shift.
The bilateral eyeballs showed normal morphology and outline; the retrobulbar structures were clear; the bilateral optic nerves were symmetrical; and no abnormal FDG uptake was observed.
Slight thickening of the mucosa in part of the right maxillary sinus, with an intact sinus wall; FDG uptake was absent.
No thickening of the nasopharyngeal wall was observed; the bilateral palatine tonsils were symmetrical; and FDG uptake was physiological.
The laryngopharynx showed no abnormalities in morphology and structure.
The bilateral parotid and submandibular glands showed normal morphology and density; and FDG uptake was physiological.
The thyroid gland showed normal morphology and size, with slightly uneven density; and no abnormalities were observed in FDG uptake.
Small lymph nodes were observed in the bilateral deep cervical spaces, submandibular region, and submental region.
The largest had a short diameter of approximately 0.6 cm, with some showing increased FDG metabolism (SUVmax = 5.3).
A lobulated mass measuring approximately 3.0*1.8*1.9 cm in cross-section was seen in the posterior segment of the left upper lobe, with spiculation around it and local pleural traction.
FDG metabolism was increased (SUVmax = 13.2).
A nodule measuring approximately 1.3*1.0 cm in cross-section was also seen around this nodule, showing increased FDG metabolism (SUVmax = 10.1).
A nodular lesion was seen in the lateral basal segment of the left lower lobe, closely adhering to the diaphragmatic pleura.
The lesion had relatively clear borders, a long diameter of approximately 1.1 cm, and showed increased FDG metabolism (SUVmax = 4.6).
Several small, pure ground-glass nodules, approximately 0.2-0.3 cm in length and with relatively clear borders, were observed in the apical segment of the right upper lobe and the posterior segments of both lower lobes.
FDG metabolism was normal.
Several scattered solid nodules and calcifications, with clear borders and approximately 0.2-0.5 cm in length, were observed in the posterior segment of the left lower lobe and the right lung.
FDG metabolism was normal.
A few linear and flocculent density shadows were also observed in both lungs, with normal FDG uptake.
There was no pleural effusion or pneumothorax bilaterally.
An FDG-enhanced lymph node, approximately 0.8 cm in short diameter and with an SUVmax of 5.9, was observed in the left hilum.
No significantly enlarged lymph nodes were observed in the right hilum or mediastinum.
The cardiomegaly was present.
Some arterial walls showed calcification.
The esophagus was not dilated, and the wall was not significantly thickened or swollen; FDG uptake was not increased.
The bilateral mammary glands showed slightly dense fibroadenomas, with no significant abnormalities in FDG metabolism.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
CT scan showed diffusely decreased liver parenchymal density, but no abnormal FDG uptake.
The main portal vein showed no significant widening, and no dilation of intrahepatic or extrahepatic bile ducts was observed.
The gallbladder showed no abnormalities in shape and size, with no thickening of the gallbladder wall.
Punctate high-density shadows were observed within the gallbladder, but local FDG uptake was normal.
The pancreas was normal in shape, with no obvious abnormal density shadows in the parenchyma.
The main pancreatic duct was not widened, and FDG uptake was normal.
The spleen was of normal shape, with a cystic lesion approximately 0.2 cm in long diameter within it; FDG uptake was normal.
The right kidney was normal in shape and size, with punctate high-density shadows within the parenchyma.
The left kidney showed a cystic low-density lesion approximately 1.1 cm in long diameter, with no FDG metabolism observed.
Small fat-density shadows, approximately 0.2 cm in long diameter, were observed in both kidneys, with absent FDG uptake.
Punctate high-density shadows were seen at the left adrenal junction, with no abnormal FDG metabolism.
No obvious abnormalities were observed on the right adrenal gland.
The stomach was generally full, with slight thickening of the antral wall and mildly increased FDG uptake (SUVmax = 3.4).
The intestines were poorly full, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
An isodense bulge was observed at the fundus of the uterus, with no abnormal FDG metabolism.
A patchy low-density lesion was observed on the cervix, with absent FDG metabolism.
No obvious abnormalities were observed in the bilateral adnexa.
A mixed-density mass, approximately 5.2*5.1 cm in cross-section, with clear borders and containing fat shadows, was seen in the left peritoneum of the pelvis; FDG metabolism was absent.
The bladder was poorly full, with no obvious positive stones.
No enlarged lymph nodes were observed in the abdomen, pelvis, or retroperitoneal region.
No obvious fluid accumulation was observed in the abdomen or pelvis.
The spinal alignment was normal, with some vertebral body margin osteophytes.
A Schmorl's node was observed at the lower margin of the L4 vertebral body.
Disc bulging was present at L3/4, L4/5, and L5/S1, but FDG uptake was normal.

Impression

1. a. A mass in the posterior segment of the left upper lobe, with elevated FDG metabolism, suggestive of peripheral lung cancer with metastatic nodules. b. A nodule in the lateral basal segment of the left lower lobe, closely attached to the diaphragm and pleura, with elevated FDG metabolism, suggesting a high probability of pleural invasion by a metastatic tumor; possible left hilar lymph node metastasis; please correlate with clinicopathology. c. Pure ground-glass nodules in the apical segment of the right upper lobe and the posterior segments of both lower lobes, with normal FDG metabolism, suggestive of chronic inflammatory nodules or atypical adenomatous hyperplasia; annual HRCT follow-up is recommended. d. Scattered chronic inflammatory nodules (solid and calcified) in the posterior segment of the left lower lobe and the right lung. Scattered chronic inflammation and remnants in both lungs. Enlarged cardiac silhouette, partial arteriosclerosis. Mild bilateral breast hyperplasia.

2. A teratoma is highly probable in the left pelvis. Small uterine fibroids; Nabothian cysts of the cervix. Specialist and ultrasound follow-up is recommended for the above.

3. Left renal cyst; bilateral renal microhamartomas are highly probable. Right renal stones or calcifications. Calcifications at the left adrenal junction. Splenic microcysts.

4. Fatty liver. Gallstones. Chronic antral gastritis.

5. Degenerative changes in the spine. Schmorl's nodes at the lower margin of the L4 vertebral body. L3/4, L4/5, and L5/S1 intervertebral disc bulges.

6. Mild age-related brain changes, deep lacunar infarcts in the brain; MRI is recommended. Minor inflammation of the right maxillary sinus. Reactive hyperplasia of bilateral deep cervical interspace, submandibular, and submental lymph nodes.

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.
