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 images showed: Normal brain morphology and structure, with a few patchy low-density shadows in the deep brain regions; FDG uptake was not significantly abnormal.
No widening of the ventricles, sulci, fissures, or cisterns was observed; the ventricles were symmetrical, and there was no midline shift.
The eyeballs were symmetrical and showed no significant abnormalities.
The maxillary sinus mucosa was thickened bilaterally, but the sinus walls were intact.
There was poor pneumatization of the right mastoid process.
The nasopharyngeal wall was not thickened, and FDG uptake was not abnormal.
The pharyngeal recesses were symmetrical bilaterally, the Eustachian tube openings were not narrowed, the infratemporal and pterygopalatine fossae were structurally normal, and the bilateral parapharyngeal spaces were clear; FDG uptake was not abnormal.
The palatine tonsils showed physiological uptake bilaterally.
The laryngopharynx was normal in morphology and structure.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The thyroid gland was normal in morphology and size, with slightly uneven density; FDG uptake was not abnormal.
Several small lymph nodes were observed in the bilateral deep cervical spaces and submandibular region, with no abnormalities in FDG metabolism.
A patchy soft tissue shadow with blurred edges and an internal cavity was observed in the posterior segment of the left upper lobe, measuring approximately 3.6*2.1*2.9cm, with increased FDG metabolism (SUVmax = 9.5).
Scattered ground-glass nodules with clear borders were observed in the anterior segment of the left upper lobe and the apical segment of the right upper lobe, with long diameters of approximately 0.6cm and 0.4cm respectively.
A small solid nodule with clear borders and a long diameter of approximately 0.3cm was observed in the posterior segment of the left upper lobe, with no increased FDG metabolism.
No pleural thickening was observed bilaterally, and there was no pleural effusion or pneumothorax bilaterally.
No significantly enlarged lymph nodes were observed in the bilateral hilar and mediastinal regions.
The cardiac silhouette was normal.
No esophageal dilation, wall thickening, or mass was observed, and FDG uptake was not increased.
The liver showed no obvious abnormalities in shape and size, with smooth liver margins and no widening of the hepatic fissure.
Plain CT scan showed no obvious abnormal density shadows in the liver parenchyma, and FDG uptake was normal.
The main portal vein showed no obvious 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 and no abnormal local FDG uptake.
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 abnormal FDG uptake.
The spleen showed no abnormalities in shape, size, density, or FDG uptake.
Both kidneys were normal in shape and size; a punctate dense shadow was seen in the right kidney, with no widening of the renal pelvis, calyces, or ureter, and no obvious abnormal FDG uptake.
A low-density nodule measuring approximately 1.7*1.3cm was seen in the right adrenal gland, with no increased FDG metabolism.
The left adrenal gland showed no obvious abnormalities on contrast.
The stomach was poorly distended, with no obvious thickening of the stomach wall and no obvious abnormal FDG uptake.
Intestinal distension was poor, with no obvious thickening or mass in the intestinal wall; FDG uptake was physiological.
The prostate was of normal size, with calcifications present; FDG uptake was not abnormally increased.
The bladder was generally full, with no obvious positive stones.
Calcifications were present in the tunica vaginalis of the left testis.
No enlarged lymph nodes were seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation was observed in the abdominal or pelvic cavities.
The spinal alignment was normal, with some vertebral body margin osteophytes and L4/5 and L5/S1 intervertebral disc bulges.
Increased FDG metabolism was observed in the bone marrow of the upper left femur, with SUVmax = 2.3.

Impression

1. a. A cavitary lesion with increased FDG metabolism in the posterior segment of the left upper lobe, highly suggestive of lung cancer, but atypical inflammatory granuloma cannot be ruled out. Please combine clinical examinations and pathology. b. Scattered ground-glass nodules in the anterior segment of the left upper lobe and the apical segment of the right upper lobe, without increased FDG metabolism, suggestive of atypical adenomatous hyperplasia or chronic inflammatory nodules. Please follow up with CT. Chronic inflammatory nodule in the posterior segment of the left upper lobe.

2. Possible right adrenal adenoma. Please compare with CT to rule out metastasis.

3. Right renal calculus. Prostatic calcification. Calcification of the tunica vaginalis in the left testis.

4. Partial vertebral osteophyte formation. L4/5 and L5/S1 intervertebral disc bulge. Increased FDG metabolism in the bone marrow of the left upper femur. MRI follow-up is recommended.

5. A few ischemic lesions in the deep brain. Bilateral maxillary sinusitis. Chronic inflammation of the right mastoid process.

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.
