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 following: Brain morphology and structure were normal, with a few patchy low-density shadows in the deep brain regions; FDG uptake showed no significant abnormalities.
No widening was observed in the ventricles, sulci, fissures, or cisterns; the ventricles were symmetrical, and midline shift was normal.
Both eyeballs were symmetrical and showed no significant abnormalities.
No thickening was observed in the paranasal sinus mucosa, and the sinus walls were intact.
No thickening was observed in the nasopharyngeal wall; FDG uptake showed no abnormalities; the pharyngeal recesses were symmetrical; there was no narrowing of the Eustachian tube openings; the infratemporal and pterygopalatine fossae were structurally normal; the parapharyngeal spaces were clear bilaterally, and FDG uptake showed no abnormalities.
Both palatine tonsils showed physiological uptake.
No abnormal density shadows were observed in the bilateral parotid and submandibular glands.
The laryngopharynx was normal in morphology and structure.
The thyroid gland was normal in shape and size, with slightly uneven density; a low-density nodule was observed in the right lobe, with a long diameter of approximately 0.5 cm; FDG uptake showed no abnormalities.
Several small lymph nodes were observed in the bilateral deep cervical spaces and submandibular region, with normal FDG metabolism.
A round soft tissue shadow, approximately 2.0*1.5cm in size, was seen in the medial segment of the right middle lobe, with clear borders and a slightly lobulated appearance; FDG metabolism was increased, with SUVmax=10.8.
Scattered ground-glass nodules were observed in both lungs, with clear borders; the largest was located in the lateral segment of the right middle lobe, with a long diameter of approximately 0.7cm.
A mixed ground-glass nodule, with clear borders and a long diameter of approximately 0.6cm, was seen in the posterior basal segment of the left lower lobe; FDG metabolism was not increased in either lung.
Scattered solid nodules were observed in both lungs, with clear borders and a long diameter of approximately 0.2-0.4cm; FDG metabolism was not increased.
Calcification was observed in the left upper lobe.
Scattered linear shadows were observed in both lungs.
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.
The esophagus showed no dilation, wall thickening, or mass; FDG uptake was not increased.
Bilateral breasts showed no significant abnormalities; FDG metabolism was normal.
The liver was normal in shape and size, with smooth borders and no widening of the hepatic fissure.
CT scan showed a low-density lesion in the right lobe of the liver with clear borders, absent FDG uptake, and a long diameter of approximately 0.7 cm.
Intrahepatic calcification was present.
The main portal vein showed no significant widening; intrahepatic and extrahepatic bile ducts were not dilated.
The gallbladder was normal in shape and size; the gallbladder wall was not thickened; local FDG uptake was normal.
The pancreas was normal in shape; no significant abnormal density shadows were seen in the parenchyma; the main pancreatic duct was not widened; FDG uptake was normal.
The spleen was normal in shape, size, density, and FDG uptake.
Both kidneys were normal in shape and size; no significant abnormal density shadows were seen in the parenchyma; the renal pelvis, calyces, and ureters were not widened; FDG uptake was normal.
Bilateral adrenal glands showed no significant abnormalities on contrast.
The stomach is poorly filled, with no obvious thickening of the stomach wall, and no significant abnormality in FDG uptake.
The intestines are poorly filled, with no obvious thickening or mass in the intestinal wall, and FDG uptake is physiological.
The uterus is normal in shape, with no abnormal density shadows, and no abnormally increased FDG uptake.
No abnormal FDG metabolism is observed in the bilateral adnexa.
The bladder is generally full, with no obvious positive stones.
No enlarged lymph nodes are seen in the abdominal cavity, pelvis, or retroperitoneal region.
No significant fluid accumulation is seen in the abdominal or pelvic cavities.
Scattered calcifications are present in the subcutaneous tissue of the abdominal and pelvic cavities and both buttocks.
A soft tissue shadow measuring approximately 1.2*0.9cm is seen in the subcutaneous tissue of the right buttock, with increased FDG metabolism (SUVmax = 2.9).
Scoliosis is present, with osteophyte formation at the margins of some vertebral bodies, L2-S1 disc bulging, calcification at the posterior margin of the L4/5 disc, and pneumothorax in the L5/S1 disc.
Systemic bone marrow FDG metabolism is normal.

Impression

1. a. Soft tissue mass in the medial segment of the right middle lobe with increased FDG metabolism, highly suggestive of peripheral lung cancer; please confirm with pathology. b. Scattered ground-glass nodules in both lungs, mixed ground-glass nodule in the posterior basal segment of the left lower lobe, no increased FDG metabolism, suggestive of atypical adenomatous hyperplasia or chronic inflammatory nodule; bilateral chronic inflammatory nodules (solid); please follow up with CT. Scattered chronic inflammation and sequelae in both lungs. Calcification in the left upper lobe.

2. A few ischemic lesions deep in the brain; please confirm with MRI.

3. Low-density nodule in the right lobe of the thyroid gland, no increased FDG metabolism, suggestive of benign; please follow up with ultrasound.

4. Cyst in the right lobe of the liver. Intrahepatic calcification.

5. Scattered subcutaneous calcifications in the abdominopelvic cavity and bilateral buttocks. Subcutaneous inflammatory nodule in the right buttock.

6. Scoliosis with degeneration. L2-S1 intervertebral disc bulge, L4/5 intervertebral disc posterior margin calcification, L5/S1 intervertebral disc gas accumulation.

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.
